When a baseball player catches a baseball, the glove "gives" or moves backward. How does this movement affect the change in momentum of the baseball? The change in momentum increases because the impact time increases. The change in momentum decreases because the force decreases. The change in momentum stays the same because the ball still comes to a stop. The change in momentum depends on the initial speed of the ball and the time to stop.

The pitch of a sound is decreased, when a sound source approaches the observer.
Explanation:
Pitch is nothing but it is a property that helps to determine whether the sound is high or low. Doppler effect helps to understand this concept easily. The pitch of the sound is mainly calculated based on the frequency of the sound wave arose from the sound source.
As the wellspring of sound waves moves toward an audience, the sound waves draw nearer together, expanding their recurrence and the pitch of the sound.

What force is required to accelerate a body with a mass of 15 kilograms at a rate of 8m/s²
As Force=Mass X Acceleration
Here F= 15 Kg and Accelerate = 8m/sq sec
So force required = 15×8 = 120N
F = 15 kg * 8 m/s²
F = 120 N
Answer B

The displacement covered in a certain time will decrease.
The speed of the object will stay constant.
The velocity of the object will change.
Answers
"Acceleration" means any change in the speed or direction of motion ... speeding up, slowing down, or turning. So . . .
-- The distance traveled in a certain time may increase or decrease.
-- The displacement covered in a certain time may increase or decrease.
-- The speed of the object may increase or decrease.
-- The velocity of the object (speed/direction) will change.
Choose 1 answer:
(Choice A) A kilogram is larger than a pound, so the scale could measure more massive rocks.
(Choice B) Accurate measurements cannot be made in pounds.
(Choice C) Pounds cannot be converted to kilograms.
(Choice D) It is easier to compare measurements when using the same unit system.
Answers
Answer:
(D). It is easier to compare measurements when using the same unit system.
Explanation:
Kilograms are the standard unit of mass in the metric system, while pounds are the standard unit of mass in the imperial system.
The two systems are not directly convertible, so it would be difficult to compare measurements made in different units.
Therefore, the teacher requires that the students make their measurements in kilograms to simplify the comparison of their results.
So, answer (D). It is easier to compare measurements when using the same unit system.
Let's see the other option:
- Choice (A) is incorrect because a kilogram is not larger than a pound. A kilogram is equal to about 2.2 pounds.
- Choice (B) is incorrect because accurate measurements can be made in pounds.
- Choice (C) is incorrect because pounds can be converted to kilograms. The conversion factor is 1 kilogram = 2.2 pounds.

Answer:
Choice D
Explanation:
The correct answer is (Choice D) It is easier to compare measurements when using the same unit system.
When conducting scientific experiments or measurements, it is crucial to maintain uniformity in the units of measurement to facilitate accurate comparisons and analysis. By requiring all students to measure the masses of rocks in kilograms, the teacher ensures consistency and eliminates any potential confusion that may arise from using different unit systems.
Using the same unit system allows for straightforward comparisons and calculations without the need for converting between units. It simplifies data analysis and interpretation, which is crucial for scientific accuracy and understanding. By standardizing the unit of measurement to kilograms, the students can directly compare the masses of rocks and draw meaningful conclusions from their data.

η = sini / sinr. i = 25, η = 1.33
1.33 = sin25° / sinr
sinr = sin25° / 1.33 = 0.4226/1.33 = 0.3177 Use a calculator.
r = sin⁻¹(0.3177)
r ≈ 18.52°
Option A.
