Answer:

350J

Explanation:

Given parameters:

Weight of bag  = 20N

Distance moved horizontally  = 35m

Force applied  = 10N

Unknown:

Work done on the bag  = ?

Solution:

Work done is the force applied to move a body through given distance.

  Work done  = Force applied x distance

So;

 Work done  = 10 x 35  = 350J

Answer:

Newton

Explanation:

The unit of force is Newton and it is given after Sir Isaac Newton for his tremendous works in this regard.

 Force is the product of mass and acceleration of a body.

    Force  = mass x acceleration  

 The unit of mass = kg

                    acceleration  = m/s²

So;

      1N  = 1kgm/s²

Therefore, the unit of force is newtons and 1N is equal to  1kgm/s²

Explanation:  

In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The battery is storing the energy but give it something to power and it'll give its energy to the object and a violin strings are like ruber band and if you play the violin it releases a new type of energy sound energy.

Answer:

Product

Explanation:

The force between two charges is given by :

[tex]F=\dfrac{kq_1q_2}{r^2}[/tex] ...(1)

Where

k is electrostatic constant

q₁ and q₂ are charges

r is the distance between charges

From equation (1), it is clear that the magnitude of the force is directly proportional to the product of charges.

Answer:

C. 2 and 4

Explanation:

my teacher went over it and the answer was that

The sections of the track in which the sled would experience an unbalanced force are: C. Sections 2 and 4.

In Science, there are two (2) main types of force that acts on an object and these include:

An unbalanced force refers to a type of force that occurs when two (2) or more forces acting on an object are unequal in magnitude, and as such, it typically results in a change of motion.

In this scenario, the sections of the track in which the sled would experience an unbalanced force are sections 2 and 4 respectively.

Answer:

A: High Frequency Wave Wave B: Low Frequency Wave Wave

Explanation:

The high-frequency waves are those that have a range of 3 to 30 MHz and have a longer wavelength that has more energy than a low-frequency wave and the more closer are the crest of the waves the more is frequency.

Low-frequency ranges from 30 to 300 kHz and ranges from 10 to 1 km and is suitable for long-distance communication. Mainly used in aircraft navigation and weather systems.

Answer:

The core of the sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into nuclei of helium (He). ... The core is the only part of the sun that produces an appreciable amount of heat through fusion.

Explanation:

By not running out of fuel (Hydrogen).

Rest assured ... When the sun runs low on Hydrogen, it'll go through several complex changes, and it'll end up at much much lower temperature, with much much lower energy output.

Answer:

D

Explanation:

The density has a formula of d = m / V.

The volumes are given as the same.

The density will be

d_lead = 113/ V

d_aluminum = 27/V

It does not matter for this question what the volume actually is. Just note that the value of the volume is the same for each ball.

A: incorrect. If the volumes are the same, the density is not the same because the masses are different.

B: incorrect. If the density of the two balls was less than water, the two balls would float. Never going to happen unless the balls are thin shells.

C: incorrect. The exact opposite is the answer.

D: Correct. This is the answer.

Answer:

He traveled 9km

Explanation:

To do this problem you need to use the equation which is Speed= distance/time and this problem gives you the speed which is 18 km/h and it gives you the time 1/2 hour so you write the equation 18= d/ 1/2 which his distance is 9km

Answer:

D. Solar panels remove most of the toxic chemicals found in the atmosphere.

People do not believe it is possible to use the sun's energy to create electricity.

Explanation:

I did the test.

Answer the term solenoid refers to a long, thin loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electric current is passed through it. Solenoids are important because they can create controlled magnetic fields and can be used as electromagnets

Answer:

Infinity

Explanation:

When you have a limit approaching infinity one method you can use is to remember that the highest power dominants all of the other ones so when we have (t^2)/t-1 like in your problem, we see that t^2 has the highest power of 2 so if that's going to infinity and it's not being divided by any powers higher than it will just be inifinity.

We have that for the Question, it can be said that  in the limit calculations below, if you need to use -â or â, enter -infinity or infinity. the limit is

From the question we are told

tafu models its position with the function

p(t)= t2 t â 1 where t>1.

in the limit calculations below, if you need to use -â or â, enter -infinity or infinity.

(a) calculate the limit

Generally the equation for the Question  is mathematically given as

[tex]p(t)=\frac{t^2}{t-1}\\\\Therefore\\\\For Lim_{\infty}\\\\We have\\\\ Lim_{t->\infty} p(t)= Lim_{t->\infty}\frac{t^2}{t-1}\\\\[/tex]

Since, the equivalent degree of numerator (t^2) is greater than that of the denominator

[tex]Lim_{t->\infty} p(t)= \infty[/tex]
