A toaster oven has a power rating of 1200W. If you cook a pizza in it for 1 hour at 450°F, how manyjoules of electrical energy are converted into heat by the toaster oven?
Answers
Answer;
= 4,320,000 joules
Explanation;
Power is the ratio of Work per unit time. When work is done in a given span of time, the ratio of work performed with respect to time is called Power.
Therefore;
Power = Work done/time
Power = 1200 Watts and t = 1 hour or 3600 seconds
Thus;
Work done = Power × time
= 1200 × 3600
= 4,320,000 joules or 4320 kJ

Sun is the only source of heat on earth. Heat from sun first passes through atmosphere and then fall on the earth's surface i.e. land and ocean.
Condensation, Radiation, Convection, Conduction transfers heat within the atmosphere and ocean such as rise of hot air, cooling and then falling is the example of convection whereas, heat from fire is the example of radiation.

The distance traveled by the object is 48 m.
The given parameters;
average speed of the object, = 6 meters per second
time of motion of the object, t = 8 s
The distance traveled by the object is calculated as follows;
where;
is the average speed of the object
Now, substitute the given values and solve for the distance traveled by the object;
Thus, the distance traveled by the object is 48 m.

Here's the formula for the force of gravity between 2 masses:
Force of gravity = G · m₁ · m₂ / D²
Take the numbers given in the question, write them into the formula,
and solve it for 'D'.
If you just want the answer and don't care to see the work,
then skip to the bottom line now.

3.2 x 10⁻⁸ nt = (6.67 x 10⁻¹¹ nt-m²/kg²) (50 kg) (60 kg) / D²
3.2 x 10⁻⁸ nt = (6.67 x 10⁻¹¹ x 50 x 60) (nt-m²) / D²
D² = (6.67 x 10⁻¹¹ x 50 x 60) (nt-m²) / (3.2 x 10⁻⁸ nt)
D² = 6.253125 m²
D = √6.253125 m² = 2.5 m (rounded)

This question involves the concept of magnification.
The distance to the magnified image will be "24 cm".
Image Distance
The magnification of the magnifying glass is given by the following formula:
where,
- q = image distance = ?
- M = Magnification = 4
- p = object distance = 6 cm
Therefore,
q = (4)(6 cm)
q = 24 cm
