Answer:

Average speed = 26.67 km/h

Explanation:

It is given that,

The first half of the journey by a body is traveled with a speed of 40 km/h and the next half is covered with a speed of 20 km/h

We need to find the average speed of the whole journey.​ When two speeds are given, the average speed is given by :

[tex]v=\dfrac{2v_1v_2}{v_1+v_2}\\\\v=\dfrac{2\times 40\times 20}{40+20}\\\\v=26.67\ km/h[/tex]

So, the average speed of the body of the whole journey is 26.67 km/h.

Answer:

Wright can be measured in pounds

Explanation:

Mass is the quantity of matter a body contains while weight is the measure of mass of a body. Weight is the product if mass and the acceleration due to gravity of a body.

If the mass of an object is known, we can determine the equivalent weight of such object and vice versa using the relationship W = mg

m is the mass if the object (in kg)

W is the weight

g is the acceleration due to gravity

g can be measured both on metre/seconds or lb/ft². This means that the weight of an object can be measured in both kgm/s² (Newton) and lb(pounds).

Also note that different object have different masses hence it is not always true to say that a bowling ball has the same mass as a golf ball.

Based on the explanation above, it can be concluded that Weight can be measured in pounds which gives the only correct statement.

The time taken for a sample to reduce by 98% is 33.86 hrs.

Half life is the time taken by a radioactive material for the radioactivity of to reduce by half its original value.

The half life equation is:

A = A₀ (½)^(t / T)

where A is the final amount, A₀ is the initial amount, t is the amount of time, and T is the half life.

Given is the half-life of a radioisotope is 6.0 hours and activity of a sample to be reduced by 98%.

Final amount will be 1 - 0.98 = 0.02

Substituting the values, we get

0.02 = 1 (½)^(t / 6)

t = 6 {log(1/0.02)/log2}

t = 33.86 hrs

Thus, time taken is 33.86 hrs.

Rmmbr... Absolute gravity means zero gravity..

No, and we don't have a zero gravity environment in space, either.

On the ISS, gravity is very much working. Here on the surface, we experience an acceleration of gravity of about 9.81 m/s^2. On the space station they experience a slightly reduced acceleration (about 9.2 m/s^2) because of their increased distance from the center of the Earth (gravity is a 1/r^2 law).

What we are actually experiencing on the ISS is a state of free-fall. Gravity is pulling the astronauts down, just as if they had stepped out of an airplane, but it is also pulling the ISS down. We feel weight on the ground because gravity pulls us down and the ground, not wanting to move, pushes back up at us.

We call the environment on the ISS weightlessness. An astronaut could stand on a scale and appear to have no weight because the scale is falling, too, and therefore can't push back up at us.

The two ways that we best simulate this environment on the Earth is by using airplanes that fly in (approximately) parabolic paths to put the inhabitants and vehicle into free-fall and by working in swimming pools where the neutral buoyancy feels similar to being in free-fall.

[tex]F= \frac{Gm1m2}{d^2}[/tex]

Where G represents universal gravitation constant, [tex]6.67*10^-^1^1 N.m^2/kg^2[/tex]

Given data

m1= 90 kg

m2= 60 kg

d= 1 m

Substituting our given data into the formula we have

[tex]F= \frac{6.67*10^-^1^1*90*60}{1^2}[/tex]

[tex]F= \frac{6.67*10^-^1^1*5.4*10^3}{1^2}\\\\F= 36*10^-^9 N[/tex]

The gravitational force between the two people in the football game is 3.6 * 10⁻⁷ N

Newton's law of gravitation states that the force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

F = Gm₁m₂/r²

G is the gravitational constant = 6.67 * 10⁻¹¹ N.m²/kg, m₁ = first mass = 90 kg, m₂ = second mass = 60 kg, r = distance = 1 m

F = Gm₁m₂/r²

F = 6.67 * 10⁻¹¹ N.m²/kg * 90 kg * 60 kg / 1² = 3.6 * 10⁻⁷ N

Answer:

speed = 50 metres/minute

Explanation:

Distance traveled = 100 metres

Time taken =- 2 minutes

Speed =[tex]\frac{Distance }{Time}[/tex]

speed =[tex]\frac{100}{2}[/tex]

speed = 50 metres/minute

The speed of a bird that flies 100 meters in 2 minutes is 0.83 m/s.

The speed is a scalar magnitude defined as the quotient of the distance traveled and the time, as follows:  

[tex] s = \frac{d}{t} [/tex]

Where:

d: is the distance = 100 m

t: is the time = 2 min

Hence, the bird's speed is:

[tex] s = \frac{d}{t} = \frac{100 m}{2 min} = 50 \frac{m}{min}*\frac{1 min}{60 s} = 0.83 m/s [/tex]

Therefore, the bird's speed is 0.83 m/s.

Answer:

= 7.88 × 10^-12 T

Explanation:

From the above question, we are told that:

Kinetic Energy of the proton is K. E = 10.0 MeV

Step 1

We convert 10.0 MeV to Joules

1 Mev = 1.602 × 10-13 Joules

10.0 MeV = 10.0 × 1.602 × 10^-13 Joules = 1.602 × 10^-12 J

Hence, the Kinectic energy of a proton = 1.602 × 10^-12 J

Step 2

Find the Speed of the Proton

The formula for Kinectic Energy =

K.E = 1/ 2 mv²

Where

m = mass of the proton

v = speed of the proton

K.E of the proton = 1.602 × 10^-12 J

Mass of the proton = 1.6726219 × 10^-27 kilograms

Speed of the proton = ?

1.602 × 10^-12J = 1/2 × 1.6726219 × 10^-27 × v²

1.602 × 10^-12J = 8.3631095 ×10^-28 × v²

v² = 1.602 × 10^-12/8.3631095 ×10^-28

v = √(1.602 × 10^-12/8.3631095 ×10^-28)

v = 43772331.227m/s

v = 4.3772331227 × 10^7m/s

Approximately = 4.4 × 10^7 m/s

Step 3

Find the Magnetic Field of that region of space

The formula for Magnetic Field =

B = m v / q r

We are told that the proton executes a circular orbit, hence,

mv = √2m(KE)

m = Mass of the proton = 1.6726219 × 10^-27 kg

K.E of the proton = 1.602 × 10^-12 J

v = speed of the proton = 4.4 × 10^7 m/s

q = Electric charge = 1.6 × 10^-19 C

r = radius of the orbit = 5.80Ã10^10 m

= 5.8 × 10^10m

Magnetic Field =

=√ (2 × 1.6726219 × 10^-27 kg × 1.602 × 10^-12 J) /( 1.6 × 10^-19 C × 5.80 × 10^10 m)

= 7.88 × 10^-12 T

The magnetic field in that region of space is approximately 7.88 × 10^-12 T

Large undersea earthquakes at tectonic plate borders frequently produce these amazing waves.

When the ocean floor at a plate boundary suddenly rises or falls, the water above it is displaced, which causes the rolling waves that will constitute a tsunami to be launched.

In the "Ring of Fire" of the Pacific Ocean, a geologically active region where tectonic movements frequently cause earthquakes and volcanoes, the majority of tsunamis, or roughly 80% of them, occur.

Tsunamis move through the ocean at speeds of up to 500 miles per hour (805 kilometers per hour), which is comparable to a jet plane.

The answer is 631.157

Explanation:

The question requested that the answer to the subtraction of 26.543 from 657.70 must be written using significant figures.

Here are a few tips about how to Identify significant figures.

1) It should be noted that the number "0" is what is usually (but not always) affected while trying to identify significant figures. Hence, all other numbers/digits are always significant. For example, 26.543 has five significant figures.

2) The zeros found between these "other numbers/digits" are also significant. For example, 2202 has four significant figures.

3) In the case of a decimal, the tailing zeros or the final zero is also significant. 657.70 and 657.07 have five significant figures.

Now, back to the question

657.70  - 26.543  = 631.157.

Our final answer does not have a zero, hence all the digits (six) are significant.

At 84.4 kg skier is on a 32.4 ° hill. Using X-Y axes tilted down the plane. The x-component of the weight is 443.2 N.

While Newton's second law of motion predicts that the ensuing acceleration is inversely proportional to the item's mass, his theory of gravity predicts that the gravitational force exerted on any object is proportionate to its mass.

According to Newton's Second Law of Motion, when a force applies on a mass, the mass accelerates (gains speed) (object).

X is the component of the weight

Wx = mg sinФ

Wx  = 84.4 kg x 9.8 m/s² x Sin 32.4°

Wx = 443.2 N

Y- Component of weight

Wy = mg cosФ

Wy = 84.4 k ку x 9.8 m/s² x COS 32.4

Wy = 698.4N

Therefore, the x-component of the weight is 443.2 N.

The x-axis is representing volume (cm³)

Unit of slope =?

Slope of a graph is simply defined as the change in y-axis divided by the change in x-axis. Mathematically it is expressed as:

Slope = change in y-axis (Δy)/change in x-axis (Δx)

Slope = Δy/Δx

Thus, with the above formula, we can obtain the unit used for measuring the slope as follow:

y-axis = mass (g)

x-axis = volume (cm³)

Slope =.?

Slope = Δy/Δx

Slope = mass (g) /volume (cm³)

Slope = g/cm³

Therefore, the derive unit used for measuring the slope is g/cm³
