Considering all the standard characteristics of acceleration, which involves the change in velocity concerning time, the statements (B), (C) and (D) are correct.
The given problem is based on the concepts and the fundamentals of acceleration. Acceleration is defined as the rate of change of velocity. Velocity is a vector quantity and is defined as speed in a given direction. Therefore, when any or both of the components of velocity is changing with time, a body is said to be accelerating i.e. acceleration involves a change of speed or change in direction, or a change in both speed and direction.
Now, as per the given problem,
A. Acceleration always involves changing speed is an incorrect statement because acceleration can occur when speed is constant but direction is changing.
B. Changing direction always involves acceleration is a correct statement because, a change in direction results in a change in velocity.
C Changing speed always involves acceleration is a correct statement because, changing speed results in a change in velocity.
D. Circular motion always involves acceleration is also a correct statement because in circular motion the direction is always changing, and this results in a change in velocity.
Thus, we can conclude that considering all the standard characteristics of acceleration, which involves the change in velocity concerning time, the statements (B), (C) and (D) are correct.

Answer:
A. Acceleration always involves changing speed.
Explanation:
Acceleration is defined as the rate of change of velocity.
Velocity is a vector quantity and is defined as speed in a given direction. Therefore, when any or both of the components of velocity is changing with time, a body is said to be accelerating i.e. acceleration involves a change of speed or change in direction, or a change in both speed and direction.
Considering the statements:
A. Acceleration always involves changing speed is false because acceleration can occur when speed is constant but direction is changing.
B. Changing direction always involves acceleration is true because, a change in direction results in a change in velocity.
C Changing speed always involves acceleration is true because, changing speed results in a change in velocity.
D. Circular motion always involves acceleration is true because in circular motion the direction is always changing, and this results in a change in velocity
Answer:
The John 's speed is 20 m/s.
The Betty's speed is 20 m/s
Explanation:
Given that,
John is traveling north at 20 meters/second and his friend Betty is traveling south at 20 meters/second.
We need to calculate the John and Betty's speeds
We know that,
The speed is a scalar quantity. its has only magnitude.
Hence, The John 's speed is 20 m/s.
The Betty's speed is 20 m/s
Answer: 192.9N and 91.1N
Explanation:
Let the force exerted by one person = X
Let the force exerted by the other person = y
Then, we can create equations
When both persons pull in the same direction, then
X + Y = 200 * 1.42
When both persons pull I'm opposite directions, then
X - Y = 200 * 0.509
Now we have
X + Y = 284
X - Y = 101.8
When we add the 2 equations together, we get
2X = 385.8
X = 385.8/2
X = 192.9
If x = 192.9, then, y = 284 - x
Y = 91.1
Therefore, one person exerts 192.9N, and the other exerts 91.1N
B. 10 trillion km
C. 300,000 km
D. 100 billion km
10 trillion km is the corrct asnwer
Answer:
B. 10 trillion km
Explanation:
“ It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. ”
