Answer:
Explanation:
Given
velocity of antelope
antelope needs to cover a horizontal distance of 20 m
considering horizontal velocity antelope needs to cover 20 m in t sec which is given by
i.e. in 2 sec antelope needs to jump and return to ground for zero vertical displacement
h=vertical displacement
a=acceleration
t=time
for, , t=1 s
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

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>
Answer:
Plants are a good starting point when looking at the carbon cycle on Earth. Plants have a process called photosynthesis that enables them to take carbon dioxide out of the atmosphere and combine it with water. Using the energy of the Sun, plants make sugars and oxygen molecules.
