<span>Cool air from the shore will travel to the sea</span>
Answer:
Maximum horizontal distance covered by both the stones will be same because the speed at which both the stones are thrown is same.
However, stone that is thrown upward will spend more time in the air as compared to the stone that is thrown downward because of the projectile and vertical component of the velocity.
Answer:
Inertia
Explanation:
The state of motion of an object is defined by its velocity the speed with a direction. Thus, inertia could be redefined as follows: Inertia: tendency of an object to resist changes in its velocity - and ( in the absence of an unbalanced force ) will remain with a zero velocity.
A). nuclear
No. There were batteries long long before we learned
how to use nuclear energy. Also, there is no danger of
exposure to radioactivity when you're working with a battery.
b). mechanical
No. A battery has no moving parts.
c). gravitational
No. No matter how high you take a battery in an airplane, or
how far you lower it into a mine-shaft, its characteristics don't
change. In fact, batteries even work on things that are in orbit.
d). chemical
Bingo.
Answer:
5 m/s
Explanation:
Work is force times distance.
W = Fd
Force is mass times acceleration.
W = ma d
Acceleration is change in velocity over change in time.
W = m Δv / Δt d
Distance over time is average velocity.
W = m Δv v_avg
W = m (v − v₀) (v + v₀) / 2
W = m (v² − v₀²) / 2
Plugging in values:
50 J = 4 kg (v² − (0 m/s)²) / 2
25 m²/s² = v²
v = 5 m/s
