A transformer has 10,000 windings on the primary side and 5,000 windings on the
secondary side. 100 volts is applied to the primary side. What is the anticipated voltage
on the secondary side? Is this a step-up or step down transformer?
Answer:
50 V; step-down transformer
Explanation:
10,000 : 5,000 = 100 : V
V = 50 V
From 100 V change to 50 V, so it is a step-down transformer
weather meaning of physics
Answer:
1. The day-to-day conditions of the atmosphere at a place with respect to elements like humidity, temperature, wind speed, rainfall, etc. is called the weather of that place.
2. Weather can be cloudy, sunny, rainy, stormy or clear. It is a part of the natural phenomenon which maintains the equilibrium in the atmosphere.
3. But conditions can be worse sometimes. When the atmospheric conditions are extreme or intense enough to cause property loss or life loss, such weather is termed as severe weather.
4. These also vary according to the altitudes, latitudes, and region and pressure differences. Tornadoes, cyclones, heavy rainfall, fog, winter storms come under this category. They are disastrous and hazardous. Proper disaster management and strategies are required to handle these conditions.

Take another look at line 1. Suppose that you use distance and time between any pair of neighboring dots to calculate speed:
speed = distance ÷ time
Will this speed be the same or different from the average speed you calculated in part F? Why?
Answer:
The time of travel and the distance between neighboring dots is always the same. So, the speed between neighboring dots is constant. This speed will be the same as the average speed in part F. hope it helps!
Can someone help me!
Answer:
Explanation:
For example 1, there is no friction, so the acceleration in example 1 is:[tex]\sum F=F=100=ma \rightarrow a=\frac{100}{50}=2 ms^{-2}[/tex]
For example 2, there is a friction, so the acceleration in example 2 is:
[tex]\sum F=F-f=100-40 = 60 = ma\rightarrow a_{2}=\frac{60}{50}=1.2 ms^{-2}[/tex]
Here we can say that "according to Newton's 2nd Law, the box in example 2 has less acceleration than in the example 1". So, the claim is denied.

A, B, and C are three successive points on a straight line. AB = 6.0 m, and BC = 10.0 m.
A small object moving along this line from rest with uniform acceleration, passes B and C, 2.0 s
and 4.0 s, respectively, after passing A. Calculate the
i)
acceleration of the body,
Answer:
1 m/s²
Explanation:
Let velocity at A be v,
Use d = v*t + at²2/2
From A to B,
6 = v(2) + a(2²)/2 = 2v + 2a, so
v + a = 3 (1)
From A to C,
6 + 10 = v(4) + a(4²)/2
16 = 4v + 8a
or, v + 2a = 4 (2)
From (1) (2), get
a = 1 m/s²

A block-spring system oscillates on a frictionless horizontal surface. The time needed for the block to complete one cycle is 0.1 sec. Determine the time needed for the block to travel from -A/2 to A/2, where A is the amplitude of motion
The time needed for the block to travel from -A/2 to A/2 is mathematically given as
t=0.5sec
What is the time needed for the block to travel from -A/2 to A/2?Generally, when the start point is the mean intial position and it goes from A/2 down through the right goes through and fro back to the mean position, and this is after it must have gone through -A/2. Hence it has finished one cycle (0.1 sec.)

Calculate the displacement in m and velocity in m/s at the following times for a rock thrown straight down with an initial velocity of 11.4 m/s from the Verrazano Narrows bridge in New York City. The roadway of this bridge is 70.0 m above the water. (Enter the magnitudes.)
(a)
0.500 s
displacement
velocity
Answer:
y = 6.92[m]
Vf = 16.305[m/s]
Explanation:
To solve this problem we must use the following kinematics equations, where we must first find the final velocity.
[tex]v_{f}=v_{i}+(g*t)[/tex]
where:
Vi = initial velocity = 11.4[m/s]
Vf = final velocity [m/s]
t = time = 0.5[s]
g = gravity acceleration = 9.81[m/s^2}
Note: the positive sign in the equation above is because the acceleration of gravity goes in the direction of the motion of the rock.
Vf = 11.4 + (9.81*0.5)
Vf = 16.305 [m/s]
Now we can calculate how far the rock goes, using the following equation:
[tex]v_{f} ^{2}= v_{i} ^{2}+(2*g*y)\\v_{f} ^{2}- v_{i}^{2} = 2*g*y\\y = \frac{v_{f} ^{2}- v_{i}^{2}}{2*g} \\y = \frac{16.305^{2}-11.4^{2} }{2*9.81}\\ y=6.92[m][/tex]
Therefore the Rock will be (70 - 6.92) = 63.07 [m] above the water level

A drone flies 8 m/s due East with respects to the wind. The wind is blowing 6 m/s due North with respects to the ground. What is the speed of the drone with repeat to the ground? A. 14m/s B. 10m/s C. 2m/s D. 20m/s
Answer:
v=10 m/s
Explanation:
Given that,
Speed of a drone is 8 m/s due East with respects to the wind
Speed of a drone 6 m/s due North with respect to the ground.
We need to find the speed of the drone with respect to the ground. Let v is the speed. It is given by the resultant of two speeds.
[tex]v=\sqrt{8^2+6^2} \\\\v=10\ m/s[/tex]
So, the speed of the drone with respect to the ground is 10 m/s.

a 3000 kg car accelerates uniformly from 15 m/s to 60 m/s in 5 seconds. determine the net force on the car during this time
Answer:
F = 2700 N
Explanation:
Given that,
Mass of a car, m = 3000 kg
Initial velocity, u = 15 m/s
Final velocity, v = 60 m/s
Time, t = 5 s
We need to find the net force on the car during this time . The net force on an object is given by the product of mass and acceleration. So,
F = ma
a is acceleration, a = (v-u)/t
[tex]F=\dfrac{m(v-u)}{t}\\\\F=\dfrac{3000\times (60-15)}{5}\\\\F=27000\ N[/tex]
So, 27000 N is the net force on the car during this time .

A spring with a force constant of 5.0×104 N/m is initially at its equilibrium length.
How much work must you do to stretch the spring 0.070 m?
How much work must you do to compress it 0.070 m?
(a) The work done in strecthing the spring is 122.5 N.
(b) The work done in compressing the spring is -122.5 N.
Work done to stretch the spring
The work done in stretching a spring is positive since the applied force acts in the same direction as the displacement.
The work done in strecthing the spring is calculated as follows;
W = ¹/₂kx²
W = ¹/₂ x (5 x 10⁴) x (0.07)²
W = 122.5 N
Work done in compressing the springThe work done in compressing the spring is negative, since the applied force acts in opposite direction to the displacement of the spring.
The work done in compressing the spring is calculated as follows;
W = -¹/₂kx²
W = -¹/₂ x (5 x 10⁴) x (0.07)²

You want to double the radius of a rotating solid sphere while keeping its kinetic energy constant. (The mass does not change.) To do this, the final angular velocity of the sphere must be Group of answer choices
The Final angular velocity of the sphere is : Half of its initial value ( W/2 )
Kinetic energy of a rotating body
Given that The kinetic energy of a rotating body ( K ) = 1/2 IW² --- ( 1 )
where : I = moment of inertia, w = angular velocity
I = [tex]\frac{2}{5} MR^{2}[/tex]
Therefore equation ( 1 ) becomes
K = [tex]\frac{1}{5}MR^2W^2[/tex] ----- ( 2 )
After doubling the radius
R' = 2R
K' = K
Mass = unchanged
therefore :
[tex]\frac{1}{5}MR'^2W'^2 = \frac{1}{5}MR^2W^2[/tex]
= ( 2R )² W'² = R²W²
Resolving equation above
Hence : W' ( new angular velocity ) = W / 2
In conclusion The Final angular velocity of the sphere is : Half of its initial value ( W / 2).
