Answer:

the time taken for the box to stop is 3.6 s.

Explanation:

Given;

initial speed with which the box was pushed, u = 5 m/s

time taken for the box to stop, t = 1.5 s

Assuming the box is moving at constant acceleration, a;

[tex]a = \frac{u}{t} \\\\a = \frac{5}{1.5} \\\\a = 3.33 \ m/s[/tex]

When the box is pushed a speed of 12 m/s, the time taken for the box to stop is calculated as;

[tex]t = \frac{v}{a} \\\\t = \frac{12}{3.33} \\\\t = 3.6 \ s[/tex]

Therefore, the time taken for the box to stop is 3.6 s.

Answer:

Unbalanced forces cause acceleration.

Explanation:

They cause acceleration because one force is less or more in Newtons than the other force.

For example, let's say we have a cardboard box on the floor with no friction.

If one force is pushing the box to the right with 50 Newtons, and the second force is pushing the box to the left with 0 Newtons, the box would accelerate to the RIGHT because the forces are UNBALANCED.

Answer:

735watts

Explanation:

Power = Force*distance/time

Given

Force = mg = 50 * 9.8'

Force = 490N

distance = 3m

time = 2s

Substitute

Power = 490*3/2

Power = 1470/2

Power = 735Watts

Hence the minimum power output is 735watts

The dedicated graphics card is used when performing hardware-intensive tasks so as to ensure efficiency and balanced performance. However, it uses more power and thus produces more heat. When the cooling system is not sufficient or the room is not well ventilated, your PC begins to overheat while playing games.     Explanation: How does the second law of thermodynamics relate to the direction of heat flow? Heat of itself never flows from a cold object to a hot object. ... The second law expresses the maximum efficiency of a heat engine in terms of hot and cold temperatures. one of these answers i am not sure

actually, the question would need to give you what is the gravitational force, so let's take the average of the gravitational for me which is 10 N /kg

and the formula for finding weight is

Answer:

[tex]F=2.30\times 10^{-26}\ N[/tex]

Explanation:

The distance between two electrons, d = 0.10 m

We need to find the magnitude of the electrostatic force on an electron by another electron.

The electrostatic force between two charges is given by :

[tex]F=k\dfrac{q_1q_2}{d^2}[/tex]

Substitute all the values,

[tex]F=\dfrac{9\times 10^9\times (1.6\times 10^{-19})^2}{(0.1)^2}\\\\F=2.30\times 10^{-26}\ N[/tex]

So, the magnitude of the electrostatic force between two electrons is [tex]2.30\times 10^{-26}\ N[/tex].

It is a force imposed by one charge on another as a result of the field. The magnitude of the electrostatic force will be 2.30×10⁻²⁶N.

It is a force imposed by one charge on another as a result of the field. The electrostatic force produced by one line charge on another line charge is inverse of the square of the radius.

The electrostatic force is determined by the charge potency of each charge as well as the separation distance between them.

The given data in the problem is;

q=q₁=q₂ is the electric charge = 1.6×10⁻¹⁹C

r is the distance between the two charge=0.10 m

The formula for the electrostatic force is given by;

[tex]\rm F=\frac{ Kq_1q_2}{r^2} \\\\ \rm F=\frac{ 9\times 10^9 \times(1.6\times 10^{-19})^2}{(0.1)^2}\\\\ \rm F =2.30 \times 10^{-26} \ N[/tex]

Hence the magnitude of the electrostatic force will be 2.30×10⁻²⁶N.

==>  The total mass resting on the table is (5 kg + 3 kg) = 8 kg.

==>  The total weight of that mass is (8 kg) x (9.8 m/s) = 78.4 newtons

==>  The boxes are stacked.  So the table doesn't know if the weight on it is coming from one box, 2 boxes, 3 boxes, or 100 boxes in a stack.  The table only knows that there is a downward force of 78.4 newtons on it.

==>  The table stands in a Physics classroom, and it soaks up everything it hears there.  It knows that every action produces an equal and opposite reaction, and that forces always occur in pairs.  

Ever since the day it was only a pile of lumber out behind the hardware store in the rain, the table has known that in order to maintain the good  reputation of tables all over the world, it must resist the weight of anything placed upon it with an identical upward force.  This is the normal thing for all good tables to do, up to the ultimate structural limit of their materials and construction, and it is known as the "normal force".

So the table in your question provides a normal force of 78.4 newtons. (d)

Answer:

1. The ice molecules are at a temperature of 0°C;

2. The ice molecules are absorbing latent heat which would result in their turning to liquid water. Therefore, melting or fusion is occurring.

Note: The question did not provide any options to choose from.

Explanation:

The process of change of state occurs when heat is added or removed from a substance. For example, solid may change to a liquid when heat is added to it whereas a liquid may change to liquid when heat is removed from it.

During the process of change of state, the temperature of the substance undergoing a change of state does not change throughout the time it is undergoing the change. The temperature will begin to increase or decrease when all the molecules of the substance has undergone a change of state. The heat supplied to or removed from a substance during a change of state is known as latent heat.

When a solid changes to liquid, it is known as fusion and the heat absorbed by the solid substance is known as latent heat heat of fusion. If a liquid changes to gas, it is known as vaporization and the heat absorbed by the liquid is known as latent heat of vaporization.

In the experiment by the students above, since the temperature of the ice remains constant at 0°C when heat is supplied from the Bunsen burner to it, the following processes could be occurring:

Technically yes, it does help those objects not to float away, but that is false. gravity is not the factor that lets us watch tv, talk on the phone etc.

Gravity helps us watch television, talk on the phone, and use the Internet. This is true statement.

The goal of satellites is to achieve balance. They rotate around the globe quickly enough to avoid being entirely drawn down into the planet's center of gravity, yet slowly enough to avoid drifting out into space.

When a satellite is travelling at the right speed, the earth's gravitational attraction is just strong enough to keep it in place. A satellite must move quicker to maintain orbit the nearer it is to the earth's surface. Additionally, satellites' orbits are circular or elliptical due to the continual pull of the curved surface of the planet.

Therefore, gravity plays a crucial role in our daily lives, whether it's keeping us anchored to the planet's surface or keeping the satellites we use to communicate and learn more about our environment in orbit.
