Answer:
X = 15.88 m
Explanation:
Given:
Initial Velocity V₀ = 13.4 m/s
θ = 30.1 °
g = 9.8 m/s²
To Find horizontal distance let "X" we have to time t first.
so from motion 2nd equation at Height h = 0
h = V₀y t + 1/2 (-g) t ² (ay = -g)
0 = 13.4 sin 30.1° t - 0.5 x 9.81 x t² (V₀y = V₀ Sin θ)
⇒ t = 1.37 s
Now For Horizontal distance X, ax =0m/s²
X = V₀x t + 1/2 (ax) t ²
X = 13.4 m × cos 30.1° x 1.37 s + 0
X = 15.88 m

means that a body is in motion, and its velocity is measured in meters per second. And, that velocity is increasing by two meters per second, every second.
It is very difficult for an atom to accept a proton. It can only be done under very special circumstances. So A and C are both incorrect. I don't see how D is possible. The atom does lose 1 electron, but how it gets 21 is think air.
The answer is B which is exactly what happens.
Answer:
a. closer to 20∘C
Explanation:
= mass of pallet = 50 g = 0.050 kg
= specific heat of pallet = specific heat of iron
= Initial temperature of pellet = 200 C
= mass of water = 50 g = 0.050 kg
= specific heat of water
= Initial temperature of water = 20 C
= Final equilibrium temperature
Also given that
Using conservation of energy
Energy gained by water = Energy lost by pellet
hence the correct choice is
a. closer to 20∘C
