Answer:
kinetic energy increases with the energy which causes the particles to move faster resulting in increases collision rates and rate of diffusion.
Explanation:
<span>Balanced forces that is acting on an object will NOT cause the object to accelerate, instead it will cause Static Equilibrium-the object is at rest. For example, a book is on the table and there is a downward force because of the gravity but also there is an upward force from the surface that helps to balance the weight of an object which is called a support force. It happens that the net force of an object is equal to zero, means ALL OF THE FORCE CANCEL OUT! Which leads us to the conclusion that, balanced forces will cause an object to be at rest and not to accelerate.</span>
Answer:
3.33 m/s
Explanation:
given,
mass of bullet, m = 20 g = 0.02 Kg
speed of bullet, v = 250 m/s
mass of rifle, M = 1.5 kg
speed of recoil, u = ?
initial speed of the bullet and the rifle is zero.
using conservation of momentum
(M + m) V = m v + M u
(M + m) x 0 = 0.02 x 250 + 1.5 x u
1.5 u = -5
u = -3.33 m/s
negative sign represent that the recoil velocity is opposite to bullet velocity.
Hence, the recoil velocity is equal to 3.33 m/s
Answer:
Explanation:
All living organisms are made up of cells.
Cells are the fundamental unit of life in all organisms. They perform the basic life functions required of all living organisms.
- Unicellular organisms are made up of just a single cell
- Multi-cellular organisms have more than one cell.
They are the building block of life through which other life organisations are derived.
From the choices, any living organism should have cells.
