The Milky Way is a _____ galaxy.
Answer: The Milky Way is a BARRED SPIRAL galaxy.
The puck starts with velocity vector
Its velocity at time is
Over the 0.215 s interval, the velocity changes to
Then the acceleration must have been
which has a direction of about .
The direction of the acceleration is determined by the direction of the change in velocity. This would be calculated by subtracting the initial velocity vector from the final velocity vector. However, the calculation would involve complex trigonometric functions.
In order to find the direction of the acceleration, we need to calculate the direction of the change in velocity and that direction will be the direction of the acceleration.
To calculate the change in velocity, we subtract the initial velocity from the final velocity: (6.42 m/s, 50.0°) - (2.35 m/s, -22°). We then calculate the angle of this vector which represents the change in velocity, and hence the direction of acceleration.
However, this calculation is not straightforward because it involves vector operations and would require the use of trigonometric functions to solve. This is due to the fact that velocity is a vector, meaning it has both a magnitude and a direction. Consequently, this becomes a multi-step process involving trigonometry and physics.

b. induction.
c. static electricity.
d. friction.
Answer : The correct answer is- D) Friction.
There are three modes of charging, which are Conduction, induction, and friction.
The static electricity is produced due to the rubbing of one substance with another. This is called charing by friction.
Hence, the correct answer is friction as there is friction between carpet and the feet of person walking over it.
Walking across a carpet is an example of charge being transferred by friction. The answer is letter D. The carpet, which is at rest, will resist the motion cause by your walking. This resistive motion d the friction the carpet obtained from you and you from the carpet.
B. protostar.
C. red giant.
D. nebula.
A) Person A
B) Person B
C) Person C
D) Person D

Explanation:Making fast and simple :)
Answer:
162.78 m/s is the most probable speed of a helium atom.
Explanation:
The most probable speed:
= Boltzmann’s constant =
T = temperature of the gas
m = mass of the gas particle.
Given, m =
T = 6.4 K
Substituting all the given values :
162.78 m/s is the most probable speed of a helium atom.
