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.

a large truck has a mass of 20000kg. it is traveling at 28m/s along a staright road . calculate the kinetic energy

Semmy [17]

Answer:

The answer is

Explanation:

The kinetic energy KE of an object given it's mass and velocity can be found by using the formula

$KE = \frac{1}{2} m {v}^{2} \\$

where

m is the mass

v is the velocity

From the question

m = 20000kg

v = 28 m/s

It's kinetic energy is

$KE = \frac{1}{2} \times 20000 \times {28}^{2} \\ = 10000 \times 784$

We have the final answer as

Hope this helps you

Which of these is NOT a possible type of energy transformation?

Leona [35]

It would be A because Light energy can't be used to make a Nuclear Weapon.
Electricity turns on a light bulb so B is scientifically correct.
If potential energy can be turned to Kinetic, it can also be switched. so C is scientifically correct
Ever heard of Geothermal power plants? So D is scientifically correct.
Meanwhile, A is impossible. so it is the answer you want to choose. Because the question asked for the one which is impossible.
