Answer:

I think the heat would transfer from the engine, because of this it would cook the egg

Explanation:

hopes this helps

The thermal heat energy transfer happens when we fry an egg on a hot car engine because the thermal energy lost from the engine is utilized for cooking the egg,

It can be defined as the form of the energy in which heat is transferred from one body to another body due to their molecular movements, thermal energy is also known as heat energy.

Thermal energy transfer is utilized while cooking food in our day-to-day life, frying egg is one such example of application of the thermal energy for cooking food.

Almost two third of the heat from any thermal engine is lost to the surroundings.

When we fried an egg on a hot vehicle engine, thermal energy is transferred because thermal energy lost from the engine is used to cook the egg.

Answer:

B.) the object caused the wave to refract

Explanation:

The object has caused the wave which is traveling through the air to refract back. Thus, the correct option is B.

Refraction is the phenomena which includes the change in the direction of waves which occurs when the waves travel from one medium to another medium. Refraction is always accompanied by a wavelength and change in speed of the wave. Diffraction is the bending of waves of sound and light which takes place around the obstacles and openings.

A wave traveling through the air meets an object and bounced off its flat surface at a new angle will experience refraction of waves.

Therefore, the correct option is B.

Answer:

The mass of the other worker is 45 kg

Explanation:

The given parameters are;

The gravitational potential energy of one construction worker = The gravitational potential energy of the other construction worker

The mass of the lighter construction worker, m₁ = 90 kg

The height level of the lighter construction worker's location = h₁

The height level of the other construction worker's location = h₂ = 2·h₁

The gravitational potential energy, P.E.,  is given as follows;

P.E. = m·g·h

Where;

m = The mass of the object at height

g = The acceleration due to gravity

h = The height at which is located

Let P.E.₁ represent the gravitational potential energy of one construction worker and let P.E.₂ represent the gravitational potential energy of the other construction worker

We have;

P.E.₁ = P.E.₂

Therefore;

m₁·g·h₁ = m₂·g·h₂

h₂ = 2·h₁

We have;

m₁·g·h₁ = m₂·g·2·h₁

m₁ = 2·m₂

90 kg = 2 × m₂

m₂ = (90 kg)/2 = 45 kg

The mass of the other construction worker is 45 kg.

Answer:

22 books

Explanation:

Total number of books = 288books

Total number of schools = 6 + 7 = 13

If the books are distributed evenly, it means it was distributed in such a way that all the school has equal number of copies.

Each book will receive 288/13 copies

288/13 = 22.15

Hence the best estimate for the number of books each school received is 22 books

Answer:

Explanation:

The sealed bottle serves as an open system for the water molecules, thus heat energy can be exchanged with its surroundings. When the bottle is placed in a warm environment, there would be a gradual increase in the thermal energy of the molecules of water due to a change in the temperature of its surroundings.

Thus, the molecules of water closer to the boundary of the bottle absorbs heat, becomes lighter and changes position. This gradual process continues until all molecules attains an average temperature which equals that of the surroundings of the bottle.

Therefore, both the thermal energy and temperature of the water increases.

Explanation:

From the question we are told that

50,000 years ago,

A giant 4.5 107-kg meteor

180-m-deep hole

20,000 m/s

Generally for this problem the energy change is given as

       [tex]\triangle E=\frac{1}{2} mv^2 +mgd[/tex]

Having the potential and kinetic energy in place

Mathematically  solving for Average force[tex]F_A[/tex]

       [tex]\triangle E=F_a*d[/tex]

[tex]F_A =\frac{1/2* 4.5*10^7(20,000)^2-kg+4.5*10^7*9.81*160}{160}[/tex]

Therefore Average force [tex]F_A[/tex] is given by

Julie and Ashwin were doing an experiment in the classroom. They each had to move a 15 kg box. Julie was able to move her box, but Ashwin was only able to move his after removing half the items in the box. The true statement is Ashwin has to apply less force to lift the box because the mass has decreased.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

The equation for force is

F=ma

If m is decreased by half, then f decreases as well. It takes less force to push a lighter object across the floor. Ashwin has to apply less force to lift the box because the mass has decreased.

True regarding the force he has to apply less force to lift the box because the mass has decreased

4321 is the answer

Explanation:

because the track and the car moved same speed there their acceleration will be the same

a) The acceleration of the car and the truck are equal since  for both vehicle is 15km/h and the time taken for both vehicle is also the same 5s.

b) The acceleration of the each vehicle is 0.83334 m/s².

Given data in the question is,

Time taken for both car and truck, t = 5 seconds

Initial velocity of car, Uc =50km/hr =13.8889 m/s

Final velocity of car, Vc = 65 km/hr = 18.0556 m/s

Since the truck starts from rest,

Initial velocity of the truck Ut =0

Final velocity of the truck Vt = 15 km/hr = 4.16667 m/s

Acceleration can be defined as the rate of change of velocity.

a) The acceleration of the car and the truck are equal since  for both vehicle is 15 km/h time taken for both vehicle is also the same 5s.

b) The acceleration of each vehicle is to determine.

To determine the acceleration for car and the truck , we use the first equation of motion:

v = u+ at

Where v is the final velocity,

u is the initial velocity,

a is the acceleration,

t is the time.

Now, For the car,

13.8889 m/s = 18.0556 m/s + ( a × 5)

a = [tex]\frac{ 18.0556 m/s- 13.8889 m/s}{5}[/tex]

a = [tex]\frac{4.1667}{5}[/tex]

a = 0.83334 m/s².

Hence, the acceleration of the car is 0.83334 m/s².

For the truck,

4.16667 m/s = 0 + (a× 5)

a = [tex]\frac{0-4.16667}{5}\\[/tex]

a = [tex]\frac{4.16667}{5}[/tex]

a = 0.83334 m/s²

Hence, the acceleration of the bicycle is 0.83334 m/s².

Force  M2 exerts on tension T

T = M2 g

T = M1 g sin theta - M1 g u cos theta

Note that M1 g is exerted down the plane while the frictional force opposes this motion and will be directed in the opposite direction of M1 g

M2 g = M1 g sin theta - u M1  g cos theta

1 = 2 sin 36 - u 2 cos 36

.5 = sin 36 - u cos 36

u = (sin 36 - .5) / cos 36 = .108

Any friction less that this will result in sliding

"1.7456" would be the minimum coefficient of static friction required.

Given:

Mass,

To keep the system in equilibrium forces acting on mass "[tex]m_1[/tex]" must balance forces acting on "[tex]m_2[/tex]".

That's,

→ [tex]Forces \ on \ m_1 \ downward \ along \ ramp = Forces \ on \ m_2 \ downwards[/tex]

or,

→ [tex]m_1 g Sin \Theta + \mu_s m_1 g Cos \Theta =m_2 g[/tex]

Thus,

→ [tex]\mu_s = \frac{m_2 g - m_1 g Sin \Theta}{m_1 g Cos \Theta}[/tex]

       [tex]= \frac{m_2-m_1 Sin \ 36^{\circ}}{m_1 Cos \Theta}[/tex]

hence,

→ [tex]\mu_s = \frac{2 m_1 - m_1 Sin \ 36^{\circ}}{m_1 Cos \ 36^{\circ}}[/tex]

       [tex]= 1.7456[/tex]

Answer:

Image is between F and 2F. And the exact location is:

q = 10.84 cm

Explanation:

The convex lens form different kinds of images with different sizes and locations, for the different positions of an object. In this case, the object is placed 30.5 cm from the convex lens with a focal length of 8 cm. This means that it is the case of the object placed beyond 2F. In this case, the image formed has the following characteristics:

1. Image is real.

2. Image is inverted

3. Image is diminished

4. Image is located between F and 2F

For exact location we use the thin lens formula:

[tex]\frac{1}{f} = \frac{1}{p} + \frac{1}{q}[/tex]

where,

f = focal length = 8 cm

p = object distance = 30.5 cm

q = image distance = ?

Therefore,

[tex]\frac{1}{8\ cm} = \frac{1}{30.5\ cm} + \frac{1}{q} \\\frac{1}{8\ cm} - \frac{1}{30.5\ cm} = \frac{1}{q}[/tex]

q = 10.84 cm

Answer:

in a plane flying above Earth

Explanation:

Gravity is the force that draws  objects toward center of the earth. If you throw an object up on the earth's surface, you will notice that it will fall back to the ground due to the earth's gravitational pull on the object.

However, the further one goes from the earth's surface, the lesser the gravitational pull. Therefore the cat will experience less gravitational pull in an airplane flying at a higher altitude.

Explanation:

According to Newton's first law of motion, a body will continue to be at rest or uniform motion unless acted upon by an external force.

In this situation, once the connecting rope between the sled and the dogs breaks, the motion of the sled will reduce because it is no longer connected to the dog that is providing the motion, hence the source of motion is no longer connected to the sled

Answer: Car 5

Explanation:

Higher speeds mean higher braking times so the car with the highest braking distance was travelling the the fastest and the car with the lowest braking distance was traveling the slowest.

Braking distance = Stopping distance - Thinking distance.
