Answer:
physical because chemical always reacts
Answer: To collect and remove wastes from the body.
Explanation:
The excretory system helps to collect and remove wastes from the body in the form of urine.
Answer:
1 Ns
Explanation:
Velocity = Displacement / time taken
v = 5/25 ⇒ v = 0.2 ms⁻¹
Momentum = mass × velocity
= 5 × 0.2 = 1 Ns
Answer:
Vertical component of velocity is 9.29 m/s
Explanation:
Given that,
Velocity of projection of a projectile, v = 22 m/s
It is fired at an angle of 22°
The horizontal component of velocity is v cosθ
The vertical component of velocity is v sinθ
So, vertical component is given by :



Hence, the vertical component of the velocity is 9.29 m/s
