The acceleration of the car with the data in the table above would be

neonofarm [45]

The acceleration of the car would be 0.33 first and then it would be 0.17.

Explanation:

An applied force is a force that is applied to an object by an individual or another item. On the off chance that an individual is pushing a work area over the room, at that point there is an applied power following up on the article. The applied power is the power applied on the work area by the individual.

The net force applied to the object rises to the mass of the article increased by the measure of its acceleration. The net power following up on the soccer ball is equivalent to the mass of the soccer ball duplicated by its adjustment in speed each second (its acceleration).

50 POINTS please someone answer me these questions and only if you know it please

Which requires more energy, making soup or making toast? Explain.

➪ Making toast requires more energy according to my knowledge because soup is liquid and in liquids the particles move freely and allows heat to transfer more quickly in it. Thus, Soup is made quicker and hence requires less energy whereas a toast (piece of bread) is solid and particles are tightly packed thus they need more energy to get cooked.

What are advantages of double glazed windows?

➪ Double glazed windows are air tight and are sealed properly. They cannot be broken easily which makes it more safe. Double glazed windows reduce the amount of moisture on your window panes, as the airtight seal prevents the condensation from building up. And no condensation means the house will be warmer.

When poor people are forced to sleep outdoors in cold weather, they sometimes use newspapers for blankets. What good is this? Why?

➪ They use newspapers because they have very minute holes in it which have air trapped and that trapped air is bad conductor of heat which does not allow the heat of body to flow outside and keeps them warm.

Why are loose fitting clothes more comfortable than the tight fitting clothes in hot climates?

➪ Loose-fitting clothes allow air to pass through and allows the heat of body to flow out which makes us feel cool whereas tight fitting clothes are touched with skin and does not allow the air to pass through the pores. Thus, making loose clothes more comfortable in hot climates.

How does a thermos flask keep food hot?

➪ A thermos flask does not have any pores or holes in the outer surfacs or inner surface which creates a vaccum inside the flask and does not allow heat to escape. Hence, keeping the food hot for very long time.

The haystack maker tractor lifted 120 kg of grass to a height of 5 meters in 6 seconds. Calculate the power of the haystack make

Gelneren [198K]

Answer:

1000 Joules per second.

Explanation:

To lift that much grass 5 meters higher than it was before the tractor did work that is the product of the (force needed to overdo gravity) and (displacement):

$W = mg\Delta h=120kg\cdot 10\frac{m}{s^2}\cdot 5m = 6000J$

Power is work over the amount of time:

$P = \frac{W}{\Delta t}=\frac{6000J}{6 s} = 1000 \frac{J}{s}$

An ac generator has a maximum emf output of 150 V. What is the rms current in the circuit when the generator is connected to a 3

natima [27]

This is an insidious question. Quite frankly, I would not have
expected to see it here on Brainly. But I'm ready to play the
cards that you have dealt me.

None of the choices offered is a correct solution.

If the output of the AC generator is nice and sinusoidal, and
its maximum (peak) emf is 150 volts, then its RMS emf is

   (1/2) (150) (√2) = 106.07 volts.

The resistor's dissipation is

   Power = (current) x (voltage) .

If the resistor is dissipating its full rated 35W, then

   35W = (current) x (106.07 V)

Divide each side by 106.07 V:

   RMS Current = (35W) / (106.07 V) = 0.33 Ampere .
_________________________________________

Looking over the choices offered . . .

The largest choice ... 3.1 A ... is the current in a resistor
that is dissipating 35W if the voltage is

   (35W / 3.1A) = 11.29 volts .

The smallest choice ... 1.2 A ... is the current in a resistor
that is dissipating 35W if the voltage is

   (35W / 1.2A) = 29.17 volts .

Whatever you meant the so-called "150 V" of the generator
to represent ... whether the RMS sinusoidal, peak sinusoidal,
peak square-wave, RMS square-wave, DC, average, etc. ...
none of the choices for current, in combination with any of these
generators, would dissipate 35W.

Active listening definition

anyanavicka [17]

Answer:

Active listening is a technique that is used in counseling, training, and solving disputes or conflicts. It requires that the listener fully concentrate, understand, respond and then remember what is being said. This is opposed to other listening techniques like reflective listening and empathic listening.
