If the specific heat of water is 1.0 calorie/gram°C, how many calories are required to raise 500 grams of water 10.0°C? 510 cal 5,000 cal 50 cal 501 cal

Answers

Answer : Heat required, Q = 5000 cal

Explanation :

It is given that,

Specific heat of water, c = 1 calorie/gram °C

Mass of water, m = 500 grams

Change in temperature, $\DeltaT=10\ ^oC$

We have to found the amount of heat required. Mathematically, it can be written as :

$Q=mc\Delta T$

$Q=500* 1* 10$

Q = 5000 cal

So, the correct option is (B) " 5000 cal ".

Hence, this is the required solution.

because the snow suddenly gets too slushy, you decide to carry your 100-newton sled the rest of the way home. How much workdo you you do when you pick up your sled, lifting it 0.5meter upward? How much work do you do to carry the sled if your house is 800 meters away?

Answers

You do 50 Joule work when you pick up your sled, lifting it 0.5meter upward.

You do no work to carry the sled to your home.

What is work?

Work in physics is the energy that is transferred to or from an item when a force is applied along a displacement. For a constant force acting in the same direction as the motion, the work is simply equal to the product of the force's magnitude and the distance travelled.

When a force is applied, it is said to have a component that moves the point of application, or it is said to have positive work.

Hence, lifting it 0.5meter upward, you have to work = weight of the sled × distance × cos 0°

= 100 N × 0.5 meter × 1

= 50 Joule.

To carry the sled to your home, you have to work = weight of the sled × distance × cos 90°

= 100 N × 800 m × 0

= 0.
