Monochromatic
light passes through two parallel narrow slits and forms an interference
pattern on a screen. As the distance between the two slits is <span>decreased,
the distance between light bands in the pattern on the screen will decrease.
The answer is letter A.</span>
Answer:
Sports, friends, family, a girlfriend or someone he can talk to ,
Explanation:
The velocity 2.5 m above the ground will be 49.07 m/sec.
<h3>What is spring force?</h3>
The force required to extend or compress a spring by some distance scales linearly concerning that distance is known as the spring force. Its formula is;
F = kx
The formula for force is;
F=ma
Equating both the equation;
ma = kx
a=kx/m
a=( 185 N/m × 1.38 m) / 0.53
a = 481.6 m/s²
The speed is found by Newton's third equation of motion;
v²=u²+2as
v²=0+2as
v²=2 × 481.6 m/s² × 2.5 m
v = 49.07 m/sec
Hence the velocity 2.5 m above the ground will be 49.07 m/sec.

#SPJ1
Kinetic energy is the energy of the motion.
This is because the kinetic energy can be calculated by using the formula,
K.E.=1/2 mv^2
where, v is the velocity of moving body i.e. the body is in motion.
