Answer
given,
mass of student = 60 Kg
mass of suitcase = 10 Kg
a) Work done by picking of Suitcase is equal to zero
b) acceleration = 0.1 m/s²
distance = 2 m
Using second law conservation
F = m a
F = 10 x 0.1 = 1 N
c) Work done
W = F x s
W = 1 x 2 = 2 J
d) When the are moving with constant speed acceleration is equal to zero
F = m a
F = 10 x 0 = 0 N
W = F x s = 0 x s = 0 J
e) work done = change in kinetic energy
K.E = 2 J
Radiation that comes from the sun is being beemed at earth atmosphere
Answer:
A record player has a velocity of 33.33 RPM. How fast is the record spinning in m/s at a distance of 0.085 m from the center? [0.297 m/s] 6. A merry-go-round a.k.a “the spinny thing” is rotating at 15 RPM, and has a radius of 1.75 m A.
The cooling on earth's surface (extrusive) makes a molten rock to become glassy. The lava cools so fast that crystals don't have time to form, which makes it glassy. Hope this helps!
<h2>Answer:</h2>
The correct option is A.
A) The increased pressure, pushed the molecules closer together, and caused the marshmallow to shrink.
<h2>Explanation:</h2>
Jayden experimented, she placed the marshmallow in the syringe and sealed the end. When she depressed the plunger of the syringe, the pressure increased and pushed the molecules closer together and causes the marshmallow to shrink.
