Answer:
Explanation:
This means that the ratio of the speed of the incident beam of light in a vacuum to the speed of light in the glass is 1.5
Answer:
0.198 s
Explanation:
Consider the motion of the block before collision
= initial velocity of block as it is dropped = 0 m/s
= acceleration = - g
= time of travel
= final velocity of block before collision
Using the kinematics equation
= mass of the bullet = 0.026 kg
= velocity of block just before collision = 750 m/s
= mass of the block = 5 kg
= final velocity of bullet block after collision = gt
Using conservation of momentum
Answer:
A) 0 N
Explanation:
When the velocity is constant, acceleration is always zero
Hence putting it in the formula
F=ma
Where F is force,m is mass and a is acceleration
F=m(0)
F=0
Mass is how much matter an object contains and it is measured in kilograms, so choice A is correct: 43 kg.
Answer:
Explanation:
Velocity is changing by a constant amount -10 m/s-in second of time.Anytime an object's velocity is changing,the object is said to be accelerating;it has an acceleration.
