B is electrons and A is neutrons
Answer:
Temperature is the degree or intensity of heat present in a substance or object. Thus temperature is not a form of energy.
Explanation:
Answer:
A to B is in constant speed. b to c is speeding up. c to d is not moving. d to e is slowing down.
Explanation:
a to b is at a constant rate of acceleration. (It is speed up but it is doing it consistantly) The line is curving upwards means it is speeding up just not consistantly like a to b. c to d is not going up or down which means it is not in motion. d to e is slowing down because the line curvs down ward.
Answer:
96.7 s
Explanation:
Time of flight in projectile can be calculated thus:
T = 2 × u × sin ϴ/ g
Where;
T = time of flight (s)
u = initial velocity (m/s)
ϴ = Angle of projectile (°)
g = acceleration due to gravity (9.8m/s²)
Based on the provided information; u = 670m/s, ϴ = 45°
Hence, using T = 2.u.sin ϴ/ g
T = 2 × 670 × sin 45° ÷ 9.8
T = 1340 × 0.7071 ÷ 9.8
T = 947.52 ÷ 9.8
T = 96.68
T = 96.7s
