Answer:
B. right shoe
Explanation:
When the puck comes to a stop after it collides with the left shoe both their velocities becomes zero. This means that their relative velocities is zero as the linear momentum is conserved.
When the puck rebounds after it collides with the right shoe then the right shoe will also move as linear momentum is conserved.
For elastic collision
Hence, the right shoe will have a greater speed after collision.
Answer:
v = 72.54 m/s
Explanation:
We have,
Length of a guitar string is 0.62 m
Frequency of a guitar string is 234 Hz
For guitar string,
The velocity of the wave in the string is given by :
So, the velocity of the waves in the string is 72.54 m/s.
Total distance between Sally's house and mall = 10 kilometers
Distance covered during half way drive = Kilometers
Now, she goes back to her home.
Distance covered going back home = Kilometers
Now, she drives from home to mall.
Distance covered from Sally's home to mall = 10 kilometers
Hence, the total distance Sally traveled = 5 + 5 + 10
Total distance Sally traveled = 20 kilometers
Hence, the answer is 20 kilometers
A conductor would be any material that has the ability to permit electric current to flow through it. These materials are commonly used in electrical and electronics industries. On the other hand, an insulator would be materials having little to no conductivity and primarily used in electrical safety gears.
The sound wave is series of rarefaction and compressions traveling through substance . and the waves travel through medium like solid , liquid , and gases
