Which graph shows the correct relationship between kinetic energy and speed?

Physics
1 answer:
Mamont248 [21]3 years ago
3 0

Answer: D

Explanation:

Kinetic energy = 1/2mV^2

From the formula above, we can deduce that kinetic energy is proportional to the square of speed. That is,

K.E = V^2

Graphically, the relationship isn't linear but a positive exponential. Therefore, option D is the correct answer.

What is the gravity force between two stars with mass of 5,000,000 kg and 1,000,000 kg if the distance between them is 100 m
Luda [366]

Answer:

0.0334N

Explanation:

Given parameters:

M1  = 5 x 10⁶kg

M2  = 1 x 10⁶kg

Distance  = 100m

Unknown:

Gravitational force  = ?

Solution:

To solve this problem, we use the Newton's law of universal gravitation.

     Fg  = \frac{G m1 m2}{r^{2} }  

G is the universal gravitation constant

m is the mass

r is the distance

         Fg  = \frac{6.67 x 10^{-11} x 5 x 10^{6}  x 1 x 10^{6} }{100^{2} }   = 0.0334N

The2 archer uses a force of 120 N. The force acts on an area of 0.5 cm2 on the archer's fingers. . Calculate the pressure on the
Mkey [24]

Answer:

Pressure = 24000 N/m²

Explanation:

Given the following data;

Force = 120N

Area = 0.5cm² to meters = 0.5/100 = 0.005 m²

To find the pressure;

Pressure= force/area

Pressure= 120/0.005

Pressure = 24000 N/m²

Therefore, the pressure on the archer's fingers is 24000 Newton per meters square.
