You drop a rock into a pond, and water waves spread out in circles. (a) The waves carry water outward, away from where the rock

hit. That moving water carries energy outward. (b) The waves only make the water move up and down. No energy is carried outward from where the rock hit. (c) The waves only make the water move up and down, but the waves do carry energy outward, away from where the rock hit.

Answer:

Explanation:

wave motion is defined as the propagation of the disturbance due to continous vibration of the molecules of the medium. Waves oduced due to disturbance carry only energy but not the matter.

The waves move water up and down and carry the energy.

Therefoe, the statement "(a) The waves carry water outward away from where the rock hit. The moving water carries energy outward"is incorrect.

The waves move water up and down and carry the energy, but not matter.

Therefore, the statement "(c) The waves ony make the water move u and down. No energy is carried outward from where the rock hit" is incorrect.

When a rock is droed ito a pd, a disturbance starts from the point where the stone hits the water. The waves produced carry the energy from the starting point toother locatons over a large distance which is not possible by the single molecules of water.

Therefore, the statement "(c) The waves only make the water move up and down, but the waves do carry energy outward away from where the rock hit" is correct.

Calculate the heat gained by 100 grams of ice at -20°C in order to become water at 50°C. ( C = .5 for ice and C = 1 for water, Q
Korvikt [17]

Answer:

6008 cal

Explanation:

m_{i} = mass of ice = 100 g = 0.1 kg

c_{i}  = specific heat of ice = 0.5 cal/(kg°C)

c_{w}  = specific heat of water = 1 cal/(kg°C)

L  = Latent heat of fusion of ice = 80 J/g

T_{i}  = initial temperature of ice = - 20 °C

T_{f}  = final temperature of ice = 50 °C

Q = Heat gained

Heat gained is given as

Q = m_{i} c_{i}(0 - (T_{i}))+ m_{i}L + m_{i}c_{w}(T_{i} - 0)

Q = (100) (0.5) (0 - (- 20))+ (0.1)(80) + (100) (1)(50 - 0)

Q = 6008 cal

A 50 kg car is pushed so that it speeds up from 20 m/s to 50 m/s in 3 seconds. What is the force acting on the car?
egoroff_w [7]

Answer:

A. 500 N

Explanation:

Acceleration is change in velocity over change in time.

a = Δv / Δt

a = (50 m/s − 20 m/s) / 3 s

a = 10 m/s²

Force is mass times acceleration.

F = ma

F = (50 kg) (10 m/s²)

F = 500 N
