it's true...

Explanation:

Answer:

1) mass = force / acceleration

2) acceleration = force / mass

Explanation:

Part 1)

Force = Mass x Acceleration

Divide both sides by acceleration

force / acceleration = mass

mass = force / acceleration

Part 2)

Divide both sides by mass

force / mass = acceleration

acceleration = force / mass

Answer:

In the formula, 'X' is the temperature value to be converted, 'UFP' is the upper fixed point and 'LFP' is the lower fixed point of the temperature scale

Explanation:

LFP means Lower fixed point and UFP means Upper fixed point. Explanation: There are different scales with different lower fixed point and upper fixed point to measure temperature but the distance between these scales is same in any table or scale considered.

Answer:

Mass of the ball, M = 6.667 kg

Explanation:

Given data:

Momentum, Mo = 10.0 kgm/s

Velocity of the rolling ball, V = 1.5 m/s

Mass of the body, M = ?

Momentum, Mo = Mass, M x Velocity, V

10.0 kgm/s = M x 1.5 m/s

Divide each side by 1.5 m/s

M = 10.0 kgm/s / 1.5 m/s

M = (6⅔) kg

:. Mass of the ball, M = 6.667 kg

Explanation:

A resultant force is the sum of the forces on an object.

Forces are said to be in equilibrium when the resultant force is zero. This means the object will not accelerate.

Since the body is moving with uniform velocity, its velocity after it travels 100 m in 20 s is 15 m/s.

Hope it helps! Please do comment

Answer:

1m

Explanation:

The conversion is 1mm = 0.001m. So all we need to do to find how many mm there are in a meter, all we need to do is divide by a 1000;

1000 / 1000 = 1m

Answer:

GALELOI GALELEI:HE WAS A FAMOUS SCIENTIST WHO MADE PENDULAM ALSO HE EXPLAINED THE MOTION AND INERTIA

ISAAC NEWTON:3 LAWS OF MOTION,3 FORMULAS OF MOTION,GRAVITY

Answer:

Below

Explanation:

4. You can use this formula to calculate the acceleration of an object

     acceleration = velocity / elapsed time

Plugging our values in....

     acceleration = 1700 m/s / 25 s

                          = 68 m/s^2

5. You can use this formula to calculate the final velocity of an object

     finalvelocity = initialvelocity + (acceleration) (time)

Plugging our values in....

     finalvelocity = 1.5 m/s + (2.4 m/s^2) ( 3 seconds)

                         = 8.7 m/s

Hope this helps! Best of luck <3

Answer:

A

Explanation:

At constant speed, acceleration=0

From the formula, Fnet=ma (Resultant force= mass x acceleration), sub a=0

Fnet=0

Since the resultant force=0, the pushing force is equal to the frictional force

Answer:

1

Explanation:

B is -1 m/s but it transfers to 1

During portion B of its motion, the train would have the smallest speed because the slope of the position time graph is the lowest for portion B.

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object.

As given in the problem we have to find out for which portion of the motion the train would have the smallest speed,

As we know that speed is given by the slope of the position-time graph.

For portion C the slope of the given position-time graph is highest therefore the speed of the train would be largest for portion C.

For portion B the slope of the given position-time graph is lowest therefore the speed of the train would be lowest for portion B.

Explanation:

Hypothetically, lets say that someone gave Kim Jong boi a cup of coffee.

He gets mad at the "public servant" since it didn't contain 3 posafa43asdunds of sugar which makes him "big".

The public servant claims they added jfoaj4su38093 units of sugar, which is equivalent to 3 posafa43asdunds.

He gets mad and launches big cannons at Trump since he blames Boe Jiden.

Answer:

The sun is considered as the main source of energy since it is the source of nearly all the earth's energy. Plants produce food using sunlight, and the food we get from plants and animals also has its primary sunlight source.

Hoped it helps you.

Answer:

It is because it supplies most of our energy that we use today, directly or indirectly. It radiates light and heat or solar energy, which makes it possible to exist life on earth.

Explanation:

No, sound waves cannot travel in a vacuum. This is because sound waves are mechanical waves that need a medium (such as air and water) to travel. Sound in physics is defined as a vibration that propagates as an audible wave of pressure, through a medium such as a gas, liquid or solid.

We have that

The wombats total displacement is

[tex]d_t=2100m[/tex]

The average velocity during that time is

[tex]v_{avg}=5m/s[/tex]

From the question we are told that:

initial Velocity [tex]V_1=5m/s[/tex]

initial Time [tex]T_1=4min=>240sec[/tex]

Final Velocity [tex]V_2=4m/s[/tex]

Final time  [tex]T_2=3min=>180sec[/tex]

a)

Generally, the equation for displacement is mathematically given by

d_t=(Initial +final) displacement

Where

initial displacement

[tex]d_1=V_1*t_1\\\\d_1=5*240[/tex]

[tex]d_1=1200m[/tex]

Final displacement

[tex]d_2=V_2*t_2\\\\d_2=5*180[/tex]

[tex]d_2=900m[/tex]

Therefore

[tex]d_t=(Initial +final) displacement[/tex]

[tex]d_t=1200+900[/tex]

[tex]d_t=2100m[/tex]

b)

Generally, the equation for Average velocity is mathematically given by

[tex]v_{avg}=\frac{d_t}{t_1+t_2}[/tex]

[tex]v_{avg}=\frac{2100m}{240+180}[/tex]

[tex]v_{avg}=5m/s[/tex]

in conclusion

The wombats total displacement is

[tex]d_t=2100m[/tex]

The average velocity during that time is

[tex]v_{avg}=5m/s[/tex]
