(a)
consider the motion of the tennis ball. lets assume the velocity of the tennis ball going towards the racket as positive and velocity of tennis ball going away from the racket as negative.
m = mass of the tennis ball = 60 g = 0.060 kg
v₀ = initial velocity of the tennis ball before being hit by racket = 20 m/s
v = final velocity of the tennis ball after being hit by racket = - 39 m/s
ΔP = change in momentum of the ball
change in momentum of the ball is given as
ΔP = m (v - v₀)
inserting the above values
ΔP = (0.060) (- 39 - 20)
ΔP = - 3.54 kgm/s
hence , magnitude of change in momentum : 3.54 kgm/s

Answer:
Science - is a process that involves the collection of information and ideas supportedby evidence.
Physical properties of water:
Color: No color/colorless.
Odor: Odorless.
Taste: Tasteless.
Density: 1 g/ml.
Boiling point: 100°C.
Freezing/Melting point: 0°C.
State or phase:
Vapor: Gas.
Room temperature: Liquid.
Ice: Solid.
Hence, water is a colorless, odorless, and tasteless substance whose density is 1 g/ml. It boils at 100°C and melts at 0°C. In the vapor phase, it is in a gaseous state, at room temperature, it exists in a liquid state, and when its freezes (ice) it's in the solid state.
