The magnitude of the electric field due to the particle at the given distance is [tex]9\times 10^9 q[/tex].

The electric field strength of a charged particle is the force per unit charge in the given field.

The electric field strength of a charge is given as;

[tex]E = \frac{F}{q} \\\\E = \frac{kq}{r^2}[/tex]

where;

[tex]E = \frac{9\times 10^9 \times q}{1^2} \\\\E = 9\times 10^9 q[/tex]

Answer:

its inertia.

Inertia is the tendency of an object to continue in the state of rest or of uniform motion

Explanation:

The forces acting on the rock include Normal Force, Gravitational force & Friction force

It's possible for it to stay on the boulder because the normal force balances it's weight. also because static friction acts on the boulder up to it's limiting friction even if it were on an attempt to move as a result of air resistance. gravitational forces act upon it by mainly affecting it it's weight. as altitude increases, it's weight decreases since gravity varies from a height to another.

Answer:

the answer is b because an object in motion stays in motion

The water likely spilled because of inertia of motion such that an object in motion tends to stay in motion. So, option B is correct.

Inertia is defined as the property of matter by which it tends to continue its state of rest or uniform motion.

Here,

When you are travelling in a car, holding a cup of water in one hand and the driver of the car is forced to stop suddenly so that the water in the cup gets spilled out.

When the car was moving, the water in the cup was actually at the same speed relative to the car and cup. When the car is tend to stop suddenly, this causes a sudden change in acceleration of the car and thus the cup. As a result, the water in the cup spills out. This is due to the property of inertia that the water got spilled out.

According to the law of inertia, a body will preserve its state of rest or uniform motion unless an external force acts on it.

Here, the spilling out of water is the application of inertia of motion. That means the the water inside the cup which was moving forward and when the change in acceleration occurred, it got spilled in front of you thus tending to continue its state of motion.

Hence,

The water likely spilled because of inertia of motion such that an object in motion tends to stay in motion.

Answer:

A. put water in a container under the pot water will disappear from the container .

you produce about 20 W

Explanation:

Determine the time in which the work will be done. Here, we can take t = 60 s . Power is equal to work divided by time. In this example, P = 9000 J / 60 s = 150 W(example)

Answer:

Explanation:

To determine the power (or rate of work) produced, we can use the formula:

Power = Work / Time

Where:

Work = 140 J (joules)

Time = 7 seconds

So, we can plug in the values into the formula:

Power = 140 J / 7 s = 20 W (watts)

So, you produced 20 watts of power in 7 seconds.

It's important to note that work and power are different physical quantities. Work represents the amount of energy transferred, while power represents the rate at which that energy is transferred.

Ps= 1150 mb

Question Parameters:

Ladakh is 800 mb.

assuming that Leh is at an altitude of 3500 m and every 100 m

increase in height with respect to sea level corresponds to 10 mb pressure,

Generally, for 3500m the pressure change will be 350 mb.

Therefore,  here for the sea level pressure we need to add,

This is the correct answer

The  magnitude of the electric field strength at that position  is 2.6×10⁴ Newton/Coulomb.

An electric field is a physical field that surrounds electrically charged particles and acts as an attractor or repellent to all other charged particles in the vicinity. It can also refer to a system of charged particles' physical field. Electric charges and time-varying electric currents are the building blocks of electric fields.

Given parameters:

Charge of the point charge: Q = 4.2 × 10⁻⁶ Coulomb.

Distance of the position from the position: r = 1.2 meter.

The  magnitude of the electric field strength at that position = kQ/r²

= 9 × 10⁹ × 4.2×10⁻⁶/(1.2)² Newton/coulomb.

= 2.6×10⁴ Newton/Coulomb.

Hence, the  magnitude of the electric field strength at that position  is 2.6×10⁴ Newton/Coulomb.
