How hot or cold something is
How much heat is absent (measuring the absence if heat)
(Fun fact- there is no cold just absence of heat
1). trajectory
2). person sitting in a chair
3). 490 meters
4). 65 m/s
5). False. The projectile's displacement, velocity, and acceleration have vertical and horizontal components, but the projectile doesn't.
6). False
7). The vertical component of a projectile doesn't change due to gravity, but the vertical components of its displacement, velocity, and acceleration do.
The vertical components do NOT equal the horizontal components.
8). Decreasing if you include the effects of air resistance. Constant if you don't. Gravity has no effect on horizontal velocity.
9). We can't see the simulation. But if the projectile doesn't have jets on it, then as it travels upward, its vertical velocity must decrease, because gravity is trying to not let it get away.
10). We can't see the simulation. But if the projectile is traveling downward, we would call that "falling", and its vertical velocity must increase, because gravity is pulling it downward.
Its called condensation. condensation is <span>water that collects as droplets on a cold surface when humid air is in contact with it. aka. clouds</span>
Answer:
lesser time
Explanation:
The latent heat of fusion is defined as the amount of heat required to convert 1 gram of water into 1 gram of ice at constant temperature called melting point.
In this situation only the state of matter is changed, the temperature of the substance remains constant.
A liquid has lower latent heat rather than water, it means it requires lesser amount of heat to fuse it , so it requires lesser amount of time to melt the ice made by this liquid.
So, it requires lesser time.
So we want to know in which series would the emitted light belong if the electron in a hydrogen atom would go from the energy level n=5 to n=1. The correct answer is Lyman series. Complete Lyman series is from energy level n=6 to n=1. All of the wavelengths in the Lyman series are in the ultraviolet part of the electromagnetic spectrum.
