Answer:
find the change in momentum of the van
2.12pa of pressure is generated on the ground as a result of the weight.
<h3>How do you determine the force applied to the ground?</h3>
The formula for average pressure, P = F/A, can be used to determine average ground pressure. This is just the object's weight divided by the contact area in the ideal scenario, which is a static, uniform net force normal to level ground.
<h3>How much pressure is there at 1,000 feet?</h3>
In ideal circumstances, every 1000 feet of elevation gain results in a 1 inHg (inch of mercury) decrease in air pressure (barometer). The pressure will therefore drop to 28.92 inHg at 1000 ft MSL from 29.92 inHg at sea level (0 ft MSL) (1000 feet higher).

Answer:
W = 600 N
Explanation:
The mechanical advantage of any machine is the ratio of the load or weight to the effort applied. Hence, the general formula for mechanical advantage is as follows:
M.A = W/P
where,
M.A =Mechanical Advantage of Hammer = 10
W = Maximum force that could be generated = ?
P = Force created by me = 60 N
Therefore,
10 = W/60 N
W = 10*60 N
<u>W = 600 N</u>
Answer:
0.4
Explanation:
A concave lens is a diverging lens, so it will always have a negative focal length. Image distance is always negative for a concave lens because it forms virtual images.
From the lens formula;
1/f = 1/u+ 1/v
- 1/2 = 1/3 - 1/v
1/v = 1/3 + 1/2
v= 6/5
v= 1.2 cm
Magnification = image distance/object distance
Magnification = 1.2cm/3cm
Magnification = 0.4
