If a pendulum makes 10 oscillations in 5 seconds, what is its oscillation frequency?
Answer:
[tex] \boxed{ \rm{Frequency = 2 hertz}}[/tex]
Explanation:
We know that,
"Frequency refers to the number of occurrences of a periodic event per time and is measured in cycles/second."
According to Question,
⇒ 5 seconds = 10 oscillations
⇒ 1 second = 10/5 oscillations
⇒ 1 second = 2 oscillations
In one second, there are 2 oscillations or cycles. The unit of frequency is Hertz. Hence, the frequency is 2 Hertz.
A car is traveling 60 km/h and accelerates at a rate of 4 m/s^2 how long does it take the car to get to 90 km/h? ( please show work)
Answer:
Vf = 90km/h
(90*1000)/3600 ==>
(90*10)36
Vf = 25m/s
, Vi = 60km/h
(60*1000)/3600
16.666m/s =>16.7m/s
, a = 4m/s^2
t = ?
Explanation:
Vf = Vi + at
25m/s = 16.7m/s +4m/s^2(t)
25m/s - 16.7m/s = 4m/s^2(t)
8.3m/s = 4m/s^2(t)
8.3m/s/4m/s^2 = t
2.075s = t => 2.1s
what are the two poles of a magnet
Answer:
The end that faces the north is called the north-seeking pole, or north pole, of the magnet. The other end is called the south pole. When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges.
Explanation:
Answer:
North pole, south pole
Explanation:
The end of the pole that faces the north is the north pole, and the other end is called the south pole.
Opposite poles attract (North-South), but like poles repel (South-South, North-South).

A ball is thrown directly downward at 4 m/s from the edge of a high cliff. If needed, use g = 10 m/s2. With zero air resistance, the distance the ball falls during its third second of fall is most nearly
28 m
4 m
29 m
12 m
57 m
Answer:
57 meters
Explanation:
Let's see what variables we have in this problem:
[tex]v_i \ \ \ \ \ \ \ t \\ v_f \ \ \ \ \ \ \triangle x \\ a[/tex]Let's set the upwards direction to be positive and the downwards direction to be negative.
We are given the initial velocity, 4 m/s. Since the ball is thrown directly downward, we can say that the initial velocity = -4 m/s.
We are also given the acceleration due to gravity, and since the acceleration is pointing downwards, we can say that a = -10 m/s².
The time is also given to us; the question wants to know the vertical displacement at time = 3 seconds, so we can plug in 3 seconds for t.
Since we are solving for vertical displacement, we can use [tex]\triangle x[/tex] as one of our variables.
Now we have all of the variables except for the final velocity, [tex]v_f[/tex].
Since we are dealing with constant acceleration, we can use this constant acceleration equation:
[tex]x_f=x_i+v_it+\frac{1}{2}at^2[/tex]Subtract [tex]x_i[/tex] from both sides to get [tex]\triangle x[/tex].
[tex]\triangle x =v_it+\frac{1}{2}at^2[/tex]Substitute in the known values:
[tex]\triangle x = (-4\frac{m}{s})(3s) + \frac{1}{2}(-10\frac{m}{s^2})(3s)^2[/tex]Get rid of the units to make the equation more readable.
[tex]\triangle x = (-4)(3) + \frac{1}{2} (-10)(3)^2[/tex]Simplify the equation and solve for delta x.
[tex]\triangle x=(-12) -5(9)[/tex] [tex]\triangle x =-12-45[/tex] [tex]\triangle x = -57[/tex]The vertical displacement is -57 meters, so we can say that the distance the ball falls in 3 seconds is most nearly 57 meters.
A circuit contains a 305 ohm resistor, a 1.1 micro Farad capacitor, and a 42 mH inductor. At resonance, the impedance is determined to be 336.4 ohms. What is the resistance of the inductor?
Answer:
The resistance of the inductor at resonance is 258.76 ohms.
Explanation:
Given;
resistance of the resistor, R = 305 ohm
capacitance of the capacitor, C = 1.1 μF = 1.1 x 10⁻⁶ F
inductance of the inductor, L = 42 mH = 42 x 10⁻³ H = 0.042 H
At resonance the inductive reactance is equal to capacitive reactance.
[tex]\omega L = \frac{1}{\omega C}\\\\2\pi F_0 L = \frac{1}{2\pi F_0 C}\\\\F_0 = \frac{1}{2\pi\sqrt{LC} }[/tex]
Where;
F₀ is the resonance frequency
[tex]F_0 = \frac{1}{2\pi\sqrt{LC} } \\\\F_0 = \frac{1}{2\pi\sqrt{(0.024)(1.1*10^{-6})} }\\\\F_0 =980.4 \ Hz[/tex]
The inductive reactance is given by;
[tex]X_l = 2\pi F_0 L\\\\X_l = 2\pi (980.4)(0.042) \\\\X_l = 258.76 \ ohms[/tex]
Therefore, the resistance of the inductor at resonance is 258.76 ohms.

A coin falling through a vacuum loses no energy to friction, and yet after it hits the ground it has lost all its potential and kinetic energy. Which statement best explains why the law of conservation of energy is still valid in this case
Answer:
Explanation:
When coin is at a height and rest, it only has potential energy( by the virtue of its position). While the coin is falling its potential energy changes into kinetic energy. This means that its potential energy is decreasing and kinetic energy increases. just before its hits the ground kinetic energy is maximum and potential energy becomes zero.
When it hits the ground all its kinetic energy is converted into heat.
6. The momentum of a 30.0 g bird with a speed of 12 m.s-1 is 0.36 kg.m.s-1. What will be its momentum 12s later if a constant .02 N force due to air resistance acts on it
Answer:
Explanation:
initial momentum = .36 kg.m.s⁻¹
negative impulse = force x time = .02 x 12 = .24 kg.m.s⁻¹
final momentum - initial momentum = impulse
final momentum = initial momentum + impulse
= .36 - .24
= .12 kg.m.s⁻¹

An object floats with half its volume beneath the surface of the water. The volume of the object is 3.5 m. What is the weight of the object? The density of water is 1000 kg/m3
Answer:
Since the object is floating, the buoyant force equals the weight of the water displaced:
W = d g v where d is the density of water and v = V/2 where v is the volume of the water displaced and v = V/2 where V is the volume of the object.
W = 1000 kg/m^3 * 9.8 m/s^2 * (3.5 /2 m^3)
W = 17150 kg m / s^2 = 17150 N
When an object floats with half its volume beneath the surface of the water. If the volume of the object is 3.5 m,then the weight of the object would be 17167.5 N if the density of water is 1000 kg/m3
What is density?It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.
The density is the reciprocal of the specific volume of any substance.
The mathematical formula for density is given below
ρ =m /V
where ρ is the density of the substance
m is the mass of the substance
V is the volume of the substance
As given in the problem an object floats with half its volume beneath the surface of the water. The volume of the object is 3.5 m
The density of water is 1000 kg/m3
According to the Archimedes principle, the buoyancy force acting on the floating object is equal to the weight of the fluid displaced by it
W = ρ g V
Given the object floats with half its volume beneath the surface of the water means the volume of the water displaced is half of the volume of the object
V=3.5/2 m³
W = 1000×9.81×3.5/2
= 17167.5 N
Thus, the weight of the object is 17167.5 N

Correct displacement 4km south,2 km north, 5km south, and 5 km north
Answer:
2 km due south.
Explanation:
We need to find the displacement of 4km south,2 km north, 5km south, and 5 km north.
Let south is negative direction and north is positive direction.
The shortest path covered by an object is called its displacement.
D = -4+2-5+5
D = -2 km
So, the displacement is 2 km and it is in south direction.
Three equal point charges, each with charge 1.45 μC , are placed at the vertices of an equilateral triangle whose sides are of length 0.450 m . What is the electric potential energy U of the system? (Take as zero the potential energy of the three charges when they are infinitely far apart.)
Answer:
0.126J
Explanation:
To calculate the potential energy of the system U:
Since the charges are the same, and the charges between them are the same.
q1 =q2 = q3 are the charges, and r1=r2=r3 is the distance between their centres.
q = 1.45 μC
r = 0.450 m
1/4πE°(3q^2/r)......... 1
1/4πE° = 9 × 10^9 N⋅m^2⋅C−2,
Substitute the values into equation 1
= 9 × 10^9 N⋅m^2⋅C−2 × {3* (1.45×10^-6)^2/0.450m}
= 9 × 10^9 N⋅m^2⋅C−2×{3*2.1025^-12/0.450m}
= 9 × 10^9 N⋅m^2⋅C^−2×{6.3075^-12}/0.450m
= 9 × 10^9 N⋅m^2⋅C^−2 × 1.401^-11
= 0.12615J
= 0.126J

The mass of an object is 60kg on the surface of the earth what will be its weight on the surface of the moon
Take g as 10m/s2
Answer:
Wm = 97.2 [N]
Explanation:
We must make it clear that mass and weight are two different terms, the mass is always preserved that is to say this will never vary regardless of the location of the object. While weight is defined as the product of mass by gravitational acceleration.
W = m*g
where:
m = mass = 60 [kg]
g = gravity acceleration = 10 [m/s²]
But in order to calculate the weight of the body on the moon, we must know the gravitational acceleration of the moon. Performing a search of this value on the internet, we find that the moon's gravity is.
gm = 1.62 [m/s²]
Wm = 60*1.62
Wm = 97.2 [N]
