M = 7.0 kg, the mass of the groceries
h = 1.2 m, the elevation of the bag of groceries
The bag of groceries moves a constant velocity over the 2.7-m room.
At constant velocity, there is no applied force, and the kinetic energy remains constant.
At an elevation of 1.2 m, there is an increase in PE (potential energy) given by
V = m*g*h
= (7.0 kg)*(9.8 m/s²)*(1.2 m)
= 82.32 J
The change in PE is equal to the work done.
Answer: 82.3 J
The formula for kinetic energy is equal to 1/2mv^2, where "m" is the mass of the object (in kilograms) and "v" is equal to the velocity of the object (in meters per second). To calculate the speed, simply plug in the values and solve.
KE = 0.5mv^2
304 J = 0.5(0.3 kg)v^2 -mass converted from grams to kilograms
v = 45.02 m/s
The baseball is travelling about 45.02 meters per second.
Hope this helps!
I’m done with my homework done and I got to go to get my homework done and I got to go to get my homework done
Answer:
Explanation:
Total resistance = R₁ + R₂ + R₃
= 6 + 8 + 10
= 24 OHM
Total emf = 12 V
current I = 12 / 24 = .5 A .
Voltage across R₁ = current x resistance
= .5 x 6 = 3 V
Voltage across R₂ = current x resistance
= .5 x 8 = 4 V
Voltage across R₃ = current x resistance
= .5 x 10 = 5 V
Total volts = 3 + 4 + 5
= 12 V .
