Answer:

this is answer please mark me as brainlest

Explanation:

A force of 500N acts on the area of 2.5m2; calculate the pressure

exerted,

(Ans: 200 Pa]

b. Calculate the force applied when 400 Pa of pressure is exerted by a box

of surface area 2m2.

(Ans: 800 N]

The weight of a stone is 1400N. If it exerts a pressure of 700 Pa, calculate

the area.

(Ans: 2m]

d. A force of 2000 N acts on 5m² surface area. Calculate the pressure

exerted.

(Ans: 400 Pa]

A Ferris wheel on a California pier is 27 m high and rotates once every 32 seconds in the counterclockwise direction. When the w
Leto [7]

A) 140 degrees

First of all, we need to find the angular velocity of the Ferris wheel. We know that its period is

T = 32 s

So the angular velocity is

\omega=\frac{2\pi}{T}=\frac{2\pi}{32 s}=0.20 rad/s

Assuming the wheel is moving at constant angular velocity, we can now calculate the angular displacement with respect to the initial position:

\theta= \omega t

and substituting t = 75 seconds, we find

\theta= (0.20 rad/s)(75 s)=15 rad

In degrees, it is

15 rad: x = 2\pi rad : 360^{\circ}\\
x=\frac{(15 rad)(360^{\circ})}{2\pi}=860^{\circ} = 140^{\circ}

So, the new position is 140 degrees from the initial position at the top.

B) 2.7 m/s

The tangential speed, v, of a point at the egde of the wheel is given by

v=\omega r

where we have

\omega=0.20 rad/s

r = d/2 = (27 m)/2=13.5 m is the radius of the wheel

Substituting into the equation, we find

v=(0.20 rad/s)(13.5 m)=2.7 m/s

Horse does 200 lb while pulling a sled for 3 mi .how much work does the horse do?
Anestetic [448]
Let's convert the quantities in SI units first.
The force exerted by the horse is
F=200 lb=889.6 N
and the distance covered is
d=3 mi=4828 m
Therefore, the work done by the horse is equal to the product between the force applied and the distance:
W=Fd=(889.6 N)(4828 m)=4.29 \cdot 10^6 J
