Answer:
F = 580.75 N
Explanation:
The force can be calculated through the following formula:
where,
F = Force = ?
P = Pressure = (72 mm Hg)(133.322 Pa/1 mm Hg) = 9599.18 Pa
A = Area = (605 cm²)(1 m²/10⁴ cm²) = 0.0605 m²
Therefore,
<u>F = 580.75 N</u>
4800 meters, because 40 meters per second, 40x120=4800
A pebbled, uneven road would be easier to see at night because it minimizes the reflection of light from car’s light coming in the opposite direction. It is difficult to see when driving on the rainy day because the roadway reflects light from cars coming in the opposite <span>directions.</span>
The trough. The crest is compressed.
Answer:
kinetic energy = 20 J
Explanation:
KE = ½mv²
= ½× <u>100 </u> × 20 × 20
1000
KE = 20 J//
