Answer:
<h2>6.67 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula

f is the force
m is the mass
From the question we have

We have the final answer as
<h3>6.67 m/s²</h3>
Hope this helps you
B.. It can easily be transformed from high voltages to low voltages.
Answer:

Explanation:
As per energy conservation we can say that energy stored in the spring at the position of maximum compression must be equal to the kinetic energy of bullet and block system
so here we have

here we know that
k = 205 N/m
x = 35 cm

now by momentum conservation we know that


now plug in all values in it

now from above equation


by solving above equation we have

Visible light waves are the type of electromagnetic waves that make up the colors of the rainbow, because the rainbow is visible to us.
Answer:
The time taken by the ship to cover the distance, t = (x/25) s
Explanation:
Given data,
The initial velocity of the ship, u = 20 m/s
The final velocity of the ship, v = 30 m/s
The average velocity of the ship, V = (20 + 30)/ 2
= 25 m/s
The distance covered by the ship, d = x m
Then the time taken by the ship to cover the displacement is,
d = V x t
∴ t = d / V
Substituting the values,
t = x / 25
t = (x/25) s
Hence, the time taken by the ship to cover the distance, t = (x/25) s
