Answer:
Explanation:
Expression for relative velocity
= 
= (.54 + .82 )c/ 
= 1.36 c / 1.4428
= .94 c
β = .94
Answer:5.075N
Explanation:
Mass=0.145kg
Acceleration=35m/s^2
Force=mass x acceleration
Force=0.145 x 35
Force=5.075N
C. <span>People need time to shift between two different stimuli.</span>
<h3>Answer;</h3>
A- Potential energy
B- Kinetic energy
C- Potential energy
D - Both potential energy and kinetic energy
E- Both potential and kinetic energy
Potential energy is the energy possessed by the body while at rest. It is calculated by the formula mgh, where m is the mass of the body and h is the height, and g is the gravitational acceleration.
Kinetic energy on the other hand is the energy possessed by the body while in motion. It is calculated by the formula 1/2mv², where m is the mass and v is the velocity of the object or body in motion.
