Answer:
Volume of the sample: approximately
.
Average density of the sample: approximately
.
Assumption:
.
.- Volume of the cord is negligible.
Explanation:
<h3>Total volume of the sample</h3>
The size of the buoyant force is equal to
.
That's also equal to the weight (weight,
) of water that the object displaces. To find the mass of water displaced from its weight, divide weight with
.
.
Assume that the density of water is
. To the volume of water displaced from its mass, divide mass with density
.
.
Assume that the volume of the cord is negligible. Since the sample is fully-immersed in water, its volume should be the same as the volume of water it displaces.
.
<h3>Average Density of the sample</h3>
Average density is equal to mass over volume.
To find the mass of the sample from its weight, divide with
.
.
The volume of the sample is found in the previous part.
Divide mass with volume to find the average density.
.
M = 10kg
P = 40 kg.m/s
V= 4m/s
Formula v = p/m
V= p/m
=4okg.m/s / 10kg
=4m/s
Answer:
a sudden and terrible event in nature (such as a hurricane, tornado, or flood) that usually results in serious damage and many deaths The earthquake was one of the worst natural disasters of this century.
Explanation:
Acceleration = change in velocity/time
= 40/5
=8m/s^2
