Answer:

"0.758315 sec" is the appropriate choice.

Explanation:

The given values are:

Angular speed,

= 29 rad/s

or,

= $\frac{29}{2 \pi} \ rps$

Tire rotates,

= 3.5 times

Now,

The time interval will be:

⇒ $\Delta t=\frac{3.5}{\frac{29}{2 \pi} }$

⇒ $=\frac{2 \pi\times 3.5}{29}$

⇒ $=\frac{21.99}{29}$

⇒ $=0.758315 \ sec$

Why do you need friction to walk?

Goshia [24]

Answer:

The force of friction is a necessary force which helps us to walk on ground. The friction is generated between the shoes and the road. We press the ground and as a reaction the ground pushes us forward. The force of friction between sole and ground provides the necessary grip which pushes us forward

Which is correct about an ammeter?

s344n2d4d5 [400]

Answer:

b. The internal resistance must be much smaller than the other resistances in the circuit.

Explanation:

Ammeter is used to measure the current flowing through a circuit. It is connected in series configuration with the load. In such a scenario the resistance of the ammeter should be negligible so as to make sure that the voltage drop across the resistance of ammeter is zero and it shows the correct reading of the current in the circuit.
