The correct answers are <span>starting friction and </span>static friction

Friction slows down all forces, but starting friction slows down or stops completely the start of motion.

Answer: Option (c) is the correct answer.

Explanation:

A force helps to keep an object at rest is known as static friction. This type of friction avoids the movement of object from its initial place unless and until a larger force than the friction force is applied on the object.

Whereas sliding friction is the friction that is experienced when object is sliding. On the other hand, kinetic friction is the friction experienced when an object is moving from it initial place.

Thus, we can conclude that out of the given options the force that opposes the start of motion is referred to as static friction.

What are advantages and disadvantages of apparent solar time? How is the situation improved by introducing mean solar time and s
Nutka1998 [239]

Answer:

Advantage:  

Apparent solar time gives the exact location of sun in the sky according to your precise location.

Disadvantage:  

As the apparent solar time changes with the change in longitude. It is very difficult to track these changes in longitude. Hence, it is almost impossible to make plan for events.

Improvement in situation:

Situation can be improved using mean solar time because due to this people living in the longitude band agree upon a standard time. In this way, it is easy to plan for events.

"Suppose you tie a rock to the end of a 0.96 m long string and spin it in a horizontal circle with a constant angular velocity o
Ber [7]

Answer:

The mass of the rock is  m = 2.46406 \ kg

Explanation:

From the question we are told that

   The length of the string is  l  = 0.96 \ m

    The angular velocity is  w =  20.25 \ rad/s

     The tension on the string is T  = 970 \ N

Generally the centripetal force acting on the rock is mathematically evaluated as

       T = mlw^2

making m the subject of the formula

      m = \frac{T}{w^2 * l}

substituting values

     m = \frac{970}{(20.25^2) * (0.96)}

     m = 2.46406 \ kg

The maximum depth d_max that a diver can snorkel is set by the density of the water and the fact that human lungs can function a
kobusy [5.1K]

Answer:

0.17214 m

Explanation:

P = Pressure difference between inside and outside the chest cavity = 0.05 atm

\rho = Density of fresh water = 1000 kg/m³

\rho_d = Density of water in the Dead Sea= 1500 kg/m³

h = Height

In fresh water

P=\rho gh_1\\\Rightarrow h_1=\dfrac{P}{\rho g}\\\Rightarrow h_1=\dfrac{0.05\times 101325}{1000\times 9.81}\\\Rightarrow h_1=0.51643\ m

In dead sea

P=\rho_d gh_2\\\Rightarrow h_2=\dfrac{P}{\rho_d g}\\\Rightarrow h_2=\dfrac{0.05\times 101325}{1500\times 9.81}\\\Rightarrow h_2=0.34429\ m

The difference in height is 0.51643-0.34429 = 0.17214 m
