Given that,
Mass of the monkey, m = 16.8 kg
The acceleration due to gravity on the Earth, g = 9.8 m/s²
To find,
The gravitational force acting on the monkey.
Solution,
Gravitational force acting on the monkey is equal to its weight. It is given by :
W = mg
Putting all the values,
W = 16.8 kg × 9.8 m/s²
= 164.64 N
Hence, the gravitational force acting on the monkey is 164.64 N.
Quartzite is produced when grains of quartz in sandstone are welded together when the rock is subjected to high temperatures. Quartzite<span> or Quarzit is a hard, non-foliated metamorphic rock which was originally pure quartz sandstone. </span><span>It is formed when a quartz-rich sandstone is altered by the heat, pressure, </span>
Answer:
It would take 1 s to hear the echo.
Explanation:
Here, the sound covered a total of 340 meters, since it bounces off the canyon wall and travels back to Miles in the form of echo.
The time elapsed can be determined by,
v =
⇒ t =
where: v is the speed of sound in air (343 m/s), D is the distance of the nearest canyon (170 m).
So that,
2D = 2 x 170 = 340 m
Thus,
t =
= 0.9913 s
t = 1 s
It takes 1s for Miles to hear his echo.
This is called vaporization.
hope this helps :)
Complete Question:
What force (in N) must be exerted on the master cylinder of a hydraulic lift to support the weight of a 2100 kg car (a large car) resting on the slave cylinder
? The master cylinder has a 2.00-cm diameter and the slave has a 24.0-cm diameter
Answer:
Explanation:
Given
--- mass
--- diameter of the large cylinder
--- diameter of the slave cylinder
To do this, we apply Archimedes' principle of buoyancy which implies that:
Where
<em /><em />
<em /><em />
<em /><em />
<em /><em />

Calculating the area of the master cylinder.
Calculating the area of the slave cylinder.
Substitute these values in:
Multiply both sides by
The force exerted on the slave cylinder (F2) is calculated as:
Substitute 20580 for F2 in
<em>Hence, the force exerted on the master cylinder is approximately 142.92N</em>
