B. Accelerate before entering the curve
C. Applying the brakes only after exiting the curve
D. Apply the accelerator throughout the entire curve
Correct answer choice is:
A) Decelerate before the curve.
Explanation:
Decrease your speed before overtaking a curve. Watch out for road symbols signaling of nearing curves so that you have enough time to reduce down before driving through the curve. It is desirable to drive below the posted speed limit as you progress and drive through curves. Turn as little as probable.
For safety concerning a curve, the correct answer is:
A. Decelerate before the curve.
When approaching a curve while driving, it is essential to slow down or decelerate before entering the curve. This allows you to maintain better control of the vehicle and reduce the risk of losing traction or skidding.
By reducing your speed before entering the curve, you can handle the curve more safely and smoothly, adjusting your steering and maintaining stability throughout the turn. Accelerating into a curve or applying the brakes only after exiting the curve can lead to unsafe driving conditions and increase the likelihood of accidents. It is always safer to slow down before taking a curve to ensure a safer driving experience.

Answer:
(9/35) = 0.257
Explanation:
Box contains 9 new light bulbs and 6 used light bulbs, total number of bulbs = 15.
Probability of selecting two bulbs; a new light bulb and then, a used light bulb in that order = [(probability of selecting a new bulb) × (probability of selecting a used bulb from the rest)] = [(9/15) × (6/14)] = (9/35) = 0.257
The probability that Meredith will select a new bulb and then a used bulb in sequential order without replacement is around 26%.
The question asks about the probability of selecting a new light bulb and then a used light bulb from a box containing 9 new light bulbs and 6 used light bulbs. Probability events like these are solved using multiplication rules of probability that each event is independent.
First, the probability of picking a new bulb is 9/15 (total bulbs are 15). If you pick one out, you don't replace it, so there are only 14 bulbs left. Thus, the probability of picking a used bulb now is 6/14. Hence the probability of both events happening in order is the multiplication of both, i.e., (9/15)*(6/14) = 54/210 = 0.257 or around 26%.

The object falling near the Earth's surface is rarely under free fall because of the air resistance experienced by the body.
Explanation:
According to the Newton's law of gravitation, each and every body applies an attractive force on another body kept at a particular distance. This force experienced by the body is directly proportional to the product of the masses of the body and inversely proportional to the square of distance between them.
The Earth also pulls the body towards it by the action of the attractive gravitational force. When a body falls towards the Earth under the action of the gravitational force, it moves with an acceleration. The acceleration of the body when it falls freely under the action of gravity is termed as the free fall.
The earth's atmosphere plays a significant role in the motion of the object as it falls under the gravity. The air resistance experienced by the object reduces the acceleration of the object and therefore, the object is no longer under the free fall.
Thus, The object falling near the Earth's surface is rarely under free fall because of the air resistance experienced by the body.

Answer : D. 4 m/s
Answer:
D. 4 m/s
Explanation:
If a toy mouse has a mass of 4 kg and kinetic energy of 32 J, its speed is 4 m/s.
32 ÷ 4 = 8
8 ÷ 2 = 4
