Answer:

It's option d. an emf must exist around the boundary

Explanation:

The Faraday's law states that an emf must exist around the boundary whenever there is a change occurring in the flux of a magnetic field.

Answer:

-The air resistance statement goes with the pieces of paper statements

-The force of gravity statement goes with the dog statements

-The acceleration due to gravity goes with the two inflated balls

The object is moving with constant or uniform acceleration and in average speed

The object is de accelerating

The object deaccelerated and came to rest so fast.

The object moves slowly first then accelerated.

The object accelerated at first so fast then move with constant acceleration then again accelerated .

Answer:

wavelength = 0.28m

Explanation:

wavelength = velocity/ frequency

wavelength = 343/1210 = 0.28m

Please find attached photograph for your answer. Hope it helps. Please do comment. The option is c. 15m/s.

Answer:

Because the average speed can be 0-16 m/s. But the peak speed must be 16 m/s.

Taiwan's Taipei has the world's fastest elevators. Since peak speed is the quickest that any moving body can go, it is greater than average speed. The average speed is 15 m/s, while the top speed may reach 16 m/s.

Speed is the overall distance an item travels in a given amount of time.

speed =distance traveled /time consumed

Taiwan's Taipei has the world's fastest elevators. Because peak speed is the fastest that any moving body can move, it is why peak speed is greater than average speed.

The average speed is 15 m/s, while the top speed may reach 16 m/s.

While the average speed is an indication of the average.

Thus, the peak speed is higher than the average speed.

Answer:

the most suitable unit for expressing nuclear radius is Fermi.

Explanation:

Respiration releases energy - it is an exothermic process. This means it releases heat energy.

The process which releases thermal energy is respiration.

The energy which increase the temperature is called the thermal energy.

Biomass energy is created but can not be stored. Same way, the respiration process which releases heat in form of air from nose or mouth. This process is exothermic.

Thus, Respiration releases thermal energy.

The new approximate acceleration of the airplane will be D. 3.4 m/s2

Newton's second law of motion  states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.

Initial mass = 950 kg

mass of piolet = 65 kg

reduced mass = 950 - 65 = 885 kg

according to Newton's second law of motion

force = mass * acceleration

3000 N = 885 kg * acceleration

acceleration = 3000 / 885  = 3.39 m/s^2 = 3.4 m/s^2

correct answer is D. 3.4 m/s2

Answer:

Circled in Red...plus the scales, of course.

Explanation:

Answer:

The concept of zero net current in toroid occurs when we try to determine magnetic field induction outside toroid.

to determine magnetic field outside toroid, we consider a circular loop outside toroid as shown in figure.

to get the net enclosed current inside the loop, let us consider the crosssection AA' in toroid as shown in figure

as we see the crosssection AA' part of figure, we see that currents in the winding are in opposition directions at near to the loop

and far away from loop. Hence the concept of net current zero occurs in toroid when we try to determine

magnetic field induction outside toroid.

Answer:

Newton's first law

Explanation:

Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. Therefore, when the ice is smooth, friction gets lesser, and the force acted on that Puck will be decreased.

Answer:

The first law states that “objects at rest and objects in motion remain in motion in a straight line unless acted upon by an unbalanced force”. Keeping the ice smooth will make sure there is not friction, friction would slow the puck down

Speed = distance / time

Part 1: 40 km at 80 km per goir = 0.50 hours

Part 2: 40 km at 40 km per hour = 1 hour

The time of the trip was 1.5 hours

Total distance was 40 + 40 = 80 ins.

Speed = distance / time = 80/1.5 = 53.33 km/he ( round answer as needed)

When the object is submerged in methanol, it displaces an amount of methanol with weight 1.052 N, i.e. with mass = (1.052 N)/g ≈ 107.347 g. With a density of 0.8 g/cm³, this means the displaced methanol and hence the object itself have a volume of

v ≈ (107.347 g) / (0.8 g/cm³) ≈ 134.184 cm³

Likewise, when submerged in benzene, the object displaces 0.951 N of benzene, whose mass is (0.951 N)/g ≈ 97.041 g with the same volume as the object. So the density d of benzene is

d ≈ (97.041 g) / (134.184 cm³) ≈ 0.723 g/cm³

The answer you are looking for is 22 mph.

Solution:

s=speed

d=distance

t=time

Setting up the formula for the speed of an object with distance and time:

s=d/t

Substituting the given values,

s=88 miles/4 hours

So, therefore, the final answer is 22 mph.
