Where does the heat come from that creates the motion for continental drift?
poizon [28]

Answer:

The heat doesn't come from any of those the heat comes from the Sun

Explanation:

But the thing that holds the heat from the Sun is the Earth's atmosphere.

When he gets hot the carbon dioxide holds in the heat but when the when oxygen it meets the heat in the air it makes it become cooler

(i) Two 110V lamps are connected in parallel. Their ratings are 150W and 200W.
LekaFEV [45]

Answer:

37.7 Ω

Explanation:

The resistance in each lamp is:

P = IV = V²/R

R = V²/P

R₁ = (110 V)² / (150 W)

R₁ = 80.67 Ω

R₂ = (110 V)² / (200 W)

R₂ = 60.5 Ω

Their combined resistance in parallel is:

1/R = 1/R₁ + 1/R₂

1/R = 1/(80.67 Ω) + 1/(60.5 Ω)

R = 34.57 Ω

So the current that goes through them is:

V = IR

I = V/R

I = (110 V) / (34.57 Ω)

I = 3.182 A

We need the same current in the new circuit.

V = IR

230 V = (3.182 A) (R₃ + 34.57 Ω)

R₃ = 37.7 Ω

We can check our answer by finding the voltage drop across this resistor:

V = I R₃

V = (3.182 A) (37.7 Ω)

V = 120 V

230 V − 120 V = 110 V, the correct voltage for the lamps.

A horizontal force of 40N is needed to pull a 60kg box across the horizontal floor at which coefficient of friction between floo
Mazyrski [523]

Answer:

Coefficient of friction is 0.068.

Work done is 320~J.

Explanation:

Given:

Mass of the box (m): 60 kg

Force needed (F): 40 N

The formula to calculate the coefficient of friction between the floor and the box is given by

F=\mu mg...................(1)

Here, \mu is the coefficient of friction and g is the acceleration due to gravity.

Substitute 40 N for F, 60 kg for m and 9.80 m/s² for g into equation (1) and solve to calculate the value of the coefficient of friction.

40 N=\mu\times60 kg\times9.80 m/s^{2} \\~~~~~\mu=\frac{40 N}{60 kg\times9.80 m/s^{2}}\\~~~~~~~=0.068

The formula to calculate the work done in overcoming the friction is given by

W=Fd..........................(2)

Here, W is the work done and d is the distance travelled.

Substitute  40 N for F and 8 m for d into equation (2) to calculate the work done.

W=40~N\times8~m\\~~~~= 320~J

Select the correct answer.
denis-greek [22]

Answer:

D) 100 kilometres/hour.

Explanation :

<u>Given</u><u> </u><u>-</u>

  • Displacement = 200 km
  • Time taken = 2 hrs.

<u>To find</u><u> </u><u>-</u>

  • Average velocity of the car.

<u>Solu</u><u>tion</u><u> </u><u>-</u>

★ Velocity = displacement/time

→ V = 200/2

→ v = 100 km/h

<u>There</u><u>fore</u><u>,</u><u> </u><u>the</u><u> </u><u>average</u><u> </u><u>veloci</u><u>ty</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>car</u><u> </u><u>is</u><u> </u><u>1</u><u>0</u><u>0</u><u> </u><u>km</u><u>/</u><u>h</u><u>.</u>
