Answer:

The potential difference across the resistor is 250 volts.

Explanation:

The potential difference V across the ends of the resistor is given by

V = IR

where I is the current through the resistor and R is is its resistance.

Now, in our case

R = 1.0*10^3\Omega,

I = 0.25 A;

therefore, the potential across is

V = 0.25A (1.0*10^3\Omega)

\boxed{V = 250volts.}

The USDA recommends that women consume about 2000 Calories per day and men consume about 2500 Calories per day. How much average
professor190 [17]

Answer:

   1500 W to 2200 W

Explanation:

Every person does work in his daily day to day life. A person needs energy in order to perform work. And the energy consumed by an individual while performing a daily work is directly responsible to the mount of oxygen consumed by the person.

The USDA is the federal agency which looks after the food and agriculture matters of the US government. It deals with and formulates different policies and laws for the country and it s people. It recommends about 2000 calories per day for women and for men it recommends about 2500 calorie per days of food intake.

Accordingly, the average power required by a human body for doing regular work is in the range of 1500 W to 2200 W.

A large truck is moving 22.0 m/s. If it’s momentum is 125,000 kg • m/s, what is the trucks mass
strojnjashka [21]

Answer:

p = mv

m = p/v = 125000/22 = 5682 kg

Explanation:

Direct application of the momentum equation

p = mv

where,

p: momentum

m: mass

v: object velocity

steps:

-------

1) check for units consistency (  SI or Imperial)

2) separate the variable you are looking for.

3) DONE! :DD

Energy energy can be transferred from one form to another we use many Indrajeet Converse in our daily life observe carefully to
aleksandr82 [10.1K]

Answer:

Find the list below.

Explanation:

Energy conversion imply the transformation of energy from one form to another. Examples of these conversions in my home include the following:

1. Chemical energy stored in food is converted to mechanical energy used in working(example sweeping)

2. Chemical energy stored in batteries are used to produce sound energy from the radio.

3. Electrical energy flowing through the wires are used to provide heat energy from the heating device.

4. Electric energy stored in the fan is converted to kinetic energy.

5. Chemical energy stored in petrol is converted to mechanical and electrical energies in the generator.

6. Electric energy supplied by the electric gas cooker is used to generate thermal energy after heating water.

7. Electrical energy flowing through the wires supply light energy in the bulbs.

8. Electric energy is converted to light and sound energy in the televisions.

9. Light energy from the sun is converted to chemical energy in the plants at the garden.

10. Electric energy is converted to sound and light energy in the kitchen blender.

If you stung by a honey bee. why we suggest rub with baking soda why?​
pickupchik [31]

Answer:

When a bee stings, it injects methanoic acid into the skin which causes immense pain and irritation. Rubbing of baking soda on the sting area gives relief because, being alkaline in nature, baking soda neutralizes the effect of methanoic acid and gives relief.
