To convert joules to watts, you need to know the time over which the energy is expended. Since power in watts is defined as energy in joules divided by time in seconds, you cannot directly convert 7000 joules to watts without knowing the time duration.
In physics, energy expended over time refers to the rate at which energy is used or transferred. This is typically measured in units like watts (Joules per second) to quantify how quickly energy is being consumed, produced, or transformed in a system.
'Joule' is a unit of energy, whereas 'watt' is a unit of power, which means the rate of using energy. The two units measure different quantities, and neither one can be converted into the other one.
Joules (J) measure energy, while watts (W) measure power. Power is the rate at which energy is expended or transferred, so 1 watt is equal to 1 joule per second. In other words, watts represent the amount of energy consumed or produced per unit of time.
Energy has units of joules.

Not enough information given to nail down an answer. 'Work' in physics is defined as force acting through a distance. The question says nothing about the forces on the baseball, and doesn't tell us anything about the direction of the 30-meters' travel, which we could use to calculate the work done on it by gravity.
To calculate the energy expended in moving a charge through a potential difference, you can use the formula: Energy (E) = Charge (Q) × Potential Difference (V) Given: Charge (Q) = 20 Coulombs Potential Difference (V) = 0.5 Volts Plugging in the values: E = 20 C × 0.5 V E = 10 Joules Therefore, the energy expended in moving a 20 Coulomb charge through a potential difference of 0.5 Volts is 10 Joules.
Yes, simply. Work done (mechanically, electrically) is numerically equal in joules to the energy expended as the work is being done. Think of it as two halves of the same coin.

the energy unit is called joules
A power of 10 kW or 10,000 watts means that 10,000 Joules of energy is converted every second. In 1 hour the energy expended is 10 kilowatt-hours which would appear as 10 units on the electricity bill.
Joules (J) measure energy, while watts (W) measure power. Power is the rate at which energy is expended or transferred, so 1 watt is equal to 1 joule per second. In other words, watts represent the amount of energy consumed or produced per unit of time.
Joules are the metric units used to measure energy. When you are working with any form of energy you state them in joules.
Joules, all energy is measured in joules.
