The amount of space an objective takes up measures by volume.
<u>Explanation:</u>
Volume is a proportion of the measure of space, unfilled column that a substance or an item takes up. The essential SI unit to volume denotes in the (cubic meter), yet volumes might be estimated in cubic centimetres, and fluids might be estimated in liters (L) or milli-liters (mL). How the volume of matter is estimated relies upon its state. The fluid's volume is estimated with an estimating holder, for example, an estimating cup or graduated chamber.
The gas volume relies upon the volume of its holder: gases able to occupy anything that space is accessible to them. The occupied space of a routinely molded strong can be determined from its measurements. For instance, the rectangle’s volume strong is the result of its width, length, and stature. The volume of a sporadically molded strong can be estimated by the uprooting technique.
Answer:
The greater weight increases the terminal velocity by acting as an extra force against gravity and air resistance.
Answer:
Explanation:
Given
mass of boy=36 kg
length of swing=3.5 m
Let T be the tension in the swing
At top point 
where v=velocity needed to complete circular path
Th-resold velocity is given by 
So apparent weight of boy will be zero at top when it travels with a velocity of 
To get the velocity at bottom conserve energy at Top and bottom
At top 
Energy at Bottom 
Comparing two as energy is conserved
Apparent weight at bottom is given by
Do you have the answer choices ?
Answer:
a) v1 = 5.52m/s
b) v2 = -1.52m/s
c) v3 = 4.62m/s
d) vt = 3.85m/s
Explanation:
The velocity of the football wide receiver is his displacement per unit time.
Velocity v = (displacement d)/time t
v = d/t .....1
For each of the cases, equation 1 would be used to calculate the velocity.
a) v1 = d1/t1
d1= 16m
t1 = 2.9s
v1 = 16m/2.9s
v1 = 5.52m/s
b) v2 = d2/t2
d2 = -2.5m
t2 = 1.65s
v2 = -2.5/1.65
v2 = -1.52m/s
c) v3 = d3/t3
d3 = 24m
t3 = 5.2s
v3 = 24/5.2
v3 = 4.62m/s
d) vt = dt/tt
dt = 16m - 2.5m + 24m = 37.5m
tt = 2.9 + 1.65 + 5.2 = 9.75s
vt = 37.5/9.75
vt = 3.85m/s
