Answer:
Explanation:
Given that,
Mass support is
M = 0.95g= 0.95/1000 = 0.00095kg
Radius of circle R = 0.205mm
r = 0.205/1000 = 0.000205m
Then, area of the circle can be determined using
A = πr²
A = π × 0.000205²
A = 1.32 × 10^-7 m²
From pressure definitions
Pressure = Force / Area
The force is perpendicular to the area
Force = weight = mg
F = mg = 0.00095 × 9.8
F = 9.31 × 10^-3 N
Then,
Pressure = Force / Area
P = F/A
P = 9.31 × 10^-3 / 1.32 × 10^-7
P = 70,530.30 N/m²
Since 1 pascal = 1 N/m²
Then,
P = 70,530.30 Pascals
Answer:
sorry but I can understand that
Answer:
B.) a wheel and axle and a lever
Explanation:
P.S - The exact question is -
Given - A wheelbarrow can be used to help lift a load, such as a pile of dirt, and then push the load across a distance. A man pushes a wheelbarrow.
To find - Which simple machines make up a wheelbarrow?
A.) a pulley and an inclined plane
B.) a wheel and axle and a lever
C.) a pulley and a wheel and axle
D.) a lever and a wedge
Proof -
The correct option is - B.) a wheel and axle and a lever
Wheelbarrows are used to carry more goods from place to place by using minimal force as compared when goods are carried by hand.
With this machine, During hauling people can save time.
Venus moves faster than earth because it move with a higher speed as compared to earth.
<h3>Is Venus move faster than earth?</h3>
Venus move with the speed of 35.02 km/s while on the other hand, the earth moves with the speed of 29.78 km/s. So due to more speed of Venus, the Venus completes its revolution earlier than earth.
So we can conclude that Venus moves faster than earth because it move with a higher speed as compared to earth.
