How are weather from ice and plants different from weathering from wind and water?
DENIUS [597]
“Weathering is the breaking down of rocks, soil and minerals as well as wood and artificial materials through contact with the Earth’s atmosphere, biota and waters. Weathering occurs in situ, roughly translated to: “with no movement”, and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity and then being transported and deposited in other locations.”

Weathering processes are of three main types: mechanical, organic and chemical weathering.

how much power is needed to lift a box with a force of 780 newtons over a distance of 2 meters in 45 seconds
-BARSIC- [3]

Answer:

<h2>34.67 W</h2>

Explanation:

Power is the rate at which work is done and can be found by using the formula

p =  \frac{w}{t}  \\

p is the power in Watts (W)

w is the workdone in joules

t is time in s

but workdone = force × distance

From the question

force = 780 N

distance = 2 m

workdone = 780 × 2 = 1560 N

Since we now have the value of workdone we can find the power

We have

p =  \frac{1560}{45}  = 34.6666666... \\

We have the final answer as

<h3>34.67 W</h3>

Hope this helps you

While driving fast around a sharp right turn, you find yourself pressing against the car door. What is happening?
sergiy2304 [10]

Answer:

option C

Explanation:

The correct answer is option C

When the driver takes the sharp right turn the door will exert rightward pressure on the driver.

When the driver takes the sudden right turn the tendency of the body is to be in the straight line by the vehicle moves in the circular path so, as the vehicle turns it applies a rightward force on you.

The pushing of the door to you because of the centripetal force acting on the car due to sudden sharp turn.
