Answer:
A) 0.5 kg
Explanation:
Q = mCΔT
where Q is energy,
m is mass,
C is specific heat capacity,
and ΔT is temperature change.
Solving for ΔT:
ΔT = Q / (mC)
ΔT is the largest when m is the smallest.
Answer:
(a) Force and Pressure
Explanation:
Acc to the formula,
Force = Pressure/Area
Therefore it depends on force and pressure
Answer:
A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky. The wings force the air downward and that pushes the plane upward.
