Answer:
73.52983 Hp
Explanation:
m = Mass of car = 
W = Weight of car = 12000 N
a = Acceleration = 0.96 m/s²
Velocity of the car
From the question
Balancing the forces
The power is 73.52983 Hp
A. water is the universal solvent.
Answer:
a. the charge on the balloon is -1.602^-15 C
b. the charge on the hair is 1.602^-15 C
c. the force is -2.3*10^-16 N
Explanation:
a. 1 electron has charge of -1.602*10^-19 C
10,000 then has a charge of 10000*-1.602*10^-19 = -1.602^-15 C
b. The charge gained by the balloon is equal in measure but with the opposite sign to the change in the hair
c. From Coulomb's law the force is:
F = k*q1*q2/r²
where k = 9×10^9 N*m²/C², q1 and q2 are the charges, and r is the distance (in meters). Replacing with data:
F = 9×10^9*-1.602^-15*1.602^-15/0.01²
F = -2.3*10^-16 N
Answer:
zone of saturation
Explanation:
The water table is the upper limit of the zone of saturation. At the zone of saturation, the aquifers are filled with water completely. The void spaces within the rock particles are taken up by fluids.
The upper limit of this zone is the water table.
Above the water table is the zone of aeration where the pore spaces are filled within air.
During the time of recharge especially raining seasons, part of the zone of aeration are filled with water.
