An 8.10 kilogram box of mass is kept at a height of 0.99 meters above ground level. What is the potential energy of the box? (given g = 9.8 meters/second2). A. 68 joules. B. 79 joules. C. 81 joules. D. 99 joules. E. 1.0 × 102 joules

Answers

The answer is B. 79 joules.

To calculate this we will use the formula for potential energy (PE):
PE = m * g * h
where m is mass of an object, g is gravitational acceleration, h is a height at which is the object.

It s given:
m = 8.10 kg
g = 9.8 m/s²
h = 0.99 m

After replacing them in the formula for potential energy:
PE = 8.10 * 9.8 * 0.99 = 78.6 J ≈ 79 J

The answer would be 79J because when you multiply 8.1*0.99*9.8 you get 7.89, which rounds to 7.9.

While driving on a rural road, your right wheels run off the pavement. You should hold the steering wheel firmly andA: Immediately steer left, back toward the paved surface of the road.B: Steer to the right, toward the shoulder or ditch.C: Steer in a straight line while gently slowing down.

Answers

Answer:

The answer is C. Steer in a straight line while gently slowing down

Explanation:

The following are advised when your cars go off the pavement while driving;

firstly, Do not panic.

ensure you hold on to your steering wheel tightly.

keep Steering straight ahead.

ensure you Stay on the shoulder.

Ease up on the accelerator and brake gently.

When you  know you can safely do so, turn back on the road at a much lower speed.

Final answer:

When the right wheels run off the pavement while driving, you should hold the steering wheel firmly, continue driving straight, and slowly reduce your speed. This avoids the dangers of immediately steering back onto the road or towards the shoulder.

Explanation:

While driving on a rural road, if your right wheels run off the pavement, the safe response would be to hold the steering wheel firmly and steer in a straight line while gently slowing down. Immediately steering back towards the paved surface (option A) can cause your vehicle to roll or veer into oncoming traffic. Steering towards the shoulder or ditch (option B) risks hitting obstacles or further losing control. By continuing straight at a controlled, reduced speed, you can safely return to the pavement when there's a break in the roadside or ample space to move back onto the road.

Choose the answer that explains the photoelectric effect.

Answers

Photoelectric effects occurs in metals. When light or electromagnetic radiation shines upon these metals, electrons jump or are emitted freely. These emitted electrons are therefore called photoelectrons. This phenomenon can be measured in electric currents. Photoelectric effect also denotes the wave-like property of light.

Answer:

Metallic plates emit electrons only when light of a certain minimum frequency shines on them.
