Answer:The solar wind creates the magnetosphere as it pushes against and shapes Earth's magnetic field.
Explanation:
Answer:
The total energy, i.e. sum of kinetic and potential energy, is constant.
i.e. E = KE + PE
Initially, PE = 0 and KE = 1/2 mv^2
At maximum height, velocity=0, thus, KE = 0 and PE = mgh
Since, total energy is constant (KE converts to PE when the ball is rising),
therefore, KE = PE
or, 1/2 mv^2 = mgh
or, h = v^2 /2g = 13^2 / (2x9.8) = 8.622 m
Hope this helps.
Answer:
By placing the steel wool in a jar with plenty of oxygen and water, you start a chemical reaction. The iron and the oxygen react to form a new reddish-brown substance, called iron oxide or rust. In this experiment, the water level in the glass should rise as the oxygen inside combines with the iron in the steel wool.
