n object is undergoing uniform circular motion. Which of the following is/are true? I. The object is moving at constant velocity
Igoryamba

Explanation:

When an object is moving in a circular path, the motion of the object is called uniform circular motion. The object moves under the action of centripetal acceleration. It is given by :

a=\dfrac{v^2}{r}

r is the radius of circular path

v is the speed of the object

In uniform circular motion, the object moves with constant speed. Also, the velocity of the object keeps on changing because it changes direction at every instant of time. Also, the object is accelerating due to change in velocity.

So, the correct options are (b) and (c).

A 120-meter-long ski ift carries skiers from a station at the foot of a slope to a second station 40 m above. what is the IMA (i
Pepsi [2]
The ideal mechanical advantage (IMA) of an inclined plane is given by:
IMA =  \frac{L}{h}
where L is the length of the inclined plane while h is the height.
In our problem, L=120 m and h=40 m. Therefore, the IMA of the ski lift is
IMA= \frac{120 m}{40 m}=3

what mass of lead has the same volume as 1600 of alcohol ( density of lead =11300kg\m³ and density of alcohol=790kg\m³)​
Misha Larkins [42]

The mass of lead = 22,939 kg

<h3>Further explanation</h3>

Given

mass alcohol=1600 kg

The density of lead =11300kg\m³ and density of alcohol=790kg\m³

Required

mass of lead

Solution

  • volume of alcohol

\tt V=\dfrac{mass}{\rho}\\\\V=\dfrac{1600}{790}\\\\V=2.03~m^3

the volume of lead=volume of alcohol=2.03 m, so the mass of lead :

\tt m=\rho\times V\\\\m=11300\times 2.03\\\\m=22,939~kg

What is the effect of pressure on boiling and melting substance?<br>​
Nadya [2.5K]

Answer:

The boiling point of liquids always increases when pressure is applied on a liquid. This is because the molecules of a liquid will need more energy to turn into a gaseous state when pressure is applied on that substance.
