Given the amount of voltage and the amount of current drawn by the alarm clock, its resistance is 240 ohms.
Ohm’s law states that "the potential difference between two points is directly proportional to the current flowing through the resistance.
It is expressed as;
V = I × R
Where V is the voltage or potential difference, potential difference, I is the current and R is the resistance.
Given the data in the question;
We substitute our given values into the expression above.
V = I × R
120V = 0.5A × R
R = 120V / 0.5A
R = 240Ω
Therefore, given the amount of voltage and the amount of current drawn by the alarm clock, its resistance is 240 ohms.

The height of the apple from the ground can be calculated using the formula for gravitational potential energy. Given the apple's mass and its potential energy, we find that the apple is approximately 5000 meters from the ground.
The gravitational potential energy of an object can be calculated using the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity (9.8 m/s² on Earth), and h is the height of the object from the ground. In this case, the apple's gravitational potential energy is given as 175J, its mass is 0.36g (or 0.00036 kg when converted.)
To find the apple's height from the ground, you need to rearrange the formula to solve for h: h = PE / (m * g). Substituting the given values in the formula, h = 175 J / (0.00036 kg * 9.8 m/s²), you get approximately h = 5000 meters.

Answer:
It also increases
Explanation:
The strength of the gravitational force between two objects depends on two factors, mass, and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.
B. a faster wave velocity.
C. the same frequency.
D. a longer wavelength.
