Answer:

A bowling ball stored on a high shelf has more potential energy

A base ball on the same shelf should rather fall on my head

Explanation:

Potential energy =mgh where m= mass, g= gravitational force and h is height

The bowling ball is bigger and heavier than the base ball

which means more mass . The remaining parameters are constant.

This means the bowling ball has more potential energy.

Since the base ball is lighter then it’s preferable to land on someone’s head due to the lesser force it will expert and lesser pain too.

according to newton's law of inertia, a railroad train in motion should continue going forever even if its engine is turned off.
Umnica [9.8K]

Unless acted upon by an external force, an object in motion tends to stay in motion, and an object at rest prefers to stay at rest.

We can also see that we regress when a car abruptly begins to move from a condition of rest. The inertia of repose also contributes to this. Our bodies have a tendency to stay in a condition of rest, but as soon as the automobile starts moving, we start to regress.

Unless influenced by an imbalanced force, an item at rest stays at rest, and an object in motion keeps moving in a straight path at a constant pace. Second Law of Motion by Newton.

Imagine that two charged objects are the system of interest. When the objects are infinitely far from each other, the electric p
podryga [215]

Answer: Option (c) is the correct answer.

Explanation:

It is known that the expression for potential energy related to charges and distance between their separation is as follows.

           U_{q} = \frac{kq_{1}q_{2}}{r}  

where,   q_{1} and q_{2} are two charges

                r = distance of separation between the charges

               k = electrostatic constant

So, when both the charges are carry the same charge and r is small then the value of potential energy will be positive in nature.

Whereas if the distance of separation between the charges is infinitely large then the potential energy calculated will be zero everywhere.

Thus, we can conclude that the statement one object is negatively charged and the other one is positively charged, is incorrect.

The EMF does not depend on which of the following?
zaharov [31]

Answer:

Explanation:

When a wire of length L is moved with velocity v , perpendicular to magnetic field B , EMF will be produced at its two ends . EMF can be calculated with the help of following expression

EMF = BLv

As per this formula , EMF produced will not depend upon number of electrons in the magnetic field.

So B is the right choice.

Drawing a shows a displacement vector (450.0 m along the y axis). In this x, y coordinate system the scalar components are Ax 0
Alisiya [41]

Answer:

x ’= 368.61 m,  y ’= 258.11 m

Explanation:

To solve this problem we must find the projections of the point on the new vectors of the rotated system  θ = 35º

            x’= R cos 35

            y’= R sin 35

           

The modulus vector can be found using the Pythagorean theorem

            R² = x² + y²

            R = 450 m

we calculate

            x ’= 450 cos 35

            x ’= 368.61 m

            y ’= 450 sin 35

            y ’= 258.11 m
