Answer:
The motion of a projectile is a two-dimensional motion. ... This is called the principle of physical independence of motions. The velocity of the projectile can be resolved into two mutually perpendicular components: the horizontal component and the vertical component. Acceleration changes velocity.
Explanation:
V = m1 u1 - m2 u2 / m1
v = 0.01 * 500 - 2 * 1.4 / 0.01
v = 220 m/s
Answer:
Climate change, where there is an increase in the average temperature, due to continuous human activities. These activities increase greenhouse gases in the atmosphere.
Explanation:
Alaska is the largest state in the United States, and it has a cold climate. The climate changed over time as human activities such as coal mining contributed to greenhouse gas emissions leading to global warming. Over the years. the variations in weather leading to climate change melt the permafrost (frozen ground below the soil surface) causing ocean waves to erode the land and destroy property.
Parallel circuits are mostly used in houses because if you turn one light off the rest stay on. While with a series circuit, if you turn one light off, all the lights turn off as well because they are all connected to one circuit (series). Parallel is usually 2 or more circuits which is why it lets you turn one thing off and everything stays on.
