Answer and Explanation:
Data provided as per the question is as follows
Speed at point A = 20 m/s
Acceleration at point C =
The calculation of the magnitude of the acceleration at A is shown below:-
Centripetal acceleration is
now we will put the values into the above formula
=
After solving the above equation we will get
Tangential acceleration is
Answer:
Explanation:
The minimum height of a space shuttle from the surface of the earth is 304 kilometers.
So according to this data we calculate the value to g at that height.
We have the formula:
where:
g' = the acceleration due to gravity at the given height 'h' above the earth
R = radius of the earth
g = the acceleration due to gravity at the surface of the earth
Now, using eq. (1)

Specific heat of air at constant pressure = 1.005KJ/kg-K Apparently the hot air leaves the house while equal quantity of the cool air passes inside (Neglecting the small specific volume changes between the hot and the cold air) So the situation can be sampled as a scenario where there is continuous draw down of the thermal energy from the air.
Answer:
Aluminum hydrochloric acid
Explanation:
Aluminum reacts with diluted hydrochloric acid at room temperature. The metal aluminium dissolves in hydrochloric acid, producing aluminum chloride and colorless hydrogen gas. The reaction taking place between aluminium and hydrochloric acid is irreversible. And the final products will not react with each other.
