Answer:
20 degrees
Explanation:
Because projectile has the same range on both angles which on summation gives 90 degrees as a total.
Answer:
m = 4
Explanation:
We have,
You apply a force of 600 N to the branch which acts as a lever. It means it is input force, IF = 600 N
The rear of the truck weighs 2,400 N. It means it is output force, OF = 2400 N
The ratio of output force to the input force is equal to the mechanical advantage of the lever arm. It is given by :
So, the mechanical gain of the lever arm is 4.

Answer:
F = 10.788 N
Explanation:
Given that,
Charge 1,
Charge 2,
Distance between charges, d = 0.1 m
We know that there is a force between charges. It is called electrostatic force. It is given by :
So, the force applied between charges is 10.788 N.
Answer:
The speed of sound also depends on the temperature of the medium. The hotter the medium is, the faster its particles move and therefore the quicker the sound will travel through the medium. When we heat a substance, the particles in that substance have more kinetic energy and vibrate or move faster.
