How much power is 300 joules?
Power is defined as the rate at which work is done, or energy is transferred. If 300 joules of energy is transferred in 10 seconds, then the power would be 30 watts (300 J / 10 s = 30 W).
What is the potential energy of a ten kg rock that is sitting on a hill that is 300 meters high?
The potential energy of the rock is 29,430 Joules. This is calculated as the product of the mass (10 kg), gravitational acceleration (9.81 m/s^2), and height (300 m) of the rock above the ground. The formula is PE = mgh.
What is the potential energy of a 10.2 kg rock that is sitting on top of a hill that is 300 meters high?
The potential energy of the rock can be calculated using the formula: potential energy = mass × gravity × height. Given the mass of the rock (10.2 kg), the height of the hill (300 meters), and the acceleration due to gravity (approximately 9.81 m/s^2), the potential energy would be 10.2 kg × 9.81 m/s^2 × 300 m = 29970.6 Joules.
What is the kinetic energy in joules of a 0.02 kg bullet traveling 300 miles per second?
The kinetic energy of the bullet can be calculated using the formula: KE = 0.5 * m * v^2, where m is the mass and v is the velocity. Plugging in the values, KE = 0.5 * 0.02 kg * (300 m/s)^2 = 900 J. So, the kinetic energy of the bullet is 900 joules.
What is the change in the internal energy of a system that does 400 joules of work and absorbs 700 joules of heat?
400 joules.

What is the average energy transfer of a TV in joules?
If you look at your television set's nameplate, it will specify its power in watts. A watt is simply a joule per second. So, if your television is rated at, say, 300 W, then it is transferring energy at the rate of 300 joules per second.
How many joules of heat does a 100 watt heater produce if it is operated for 5 minutes?
Based on the formula, P = E/T , and 5 min is 300 seconds, 100 = E/300, E = 30000
A blender has a power of 0.3 kW. It is used to make a fruit smoothie, which takes 50 seconds. How much energy is used Give your answer in kilojoules.kJ?
To calculate the energy used by the blender, we first convert the power from kilowatts to watts: 0.3 kW = 300 watts. Then, we use the formula Energy (in joules) = Power (in watts) x Time (in seconds). Plugging in the values, we get Energy = 300 watts x 50 seconds = 15,000 joules. Finally, to convert joules to kilojoules, we divide by 1,000: 15,000 joules ÷ 1,000 = 15 kJ. Therefore, the blender uses 15 kilojoules of energy to make the fruit smoothie.

400 joules.
How much joules of heat does a 100 W of heater produce if it is operated for 5 min?
The amount of heat produced by the 100 W heater in 5 minutes can be calculated as follows: Power (in watts) = 100 W Time (in seconds) = 5 minutes * 60 seconds/minute = 300 seconds Energy = Power * Time = 100 W * 300 s = 30,000 joules So, the heater will produce 30,000 joules of heat.
How many joule is 300 fps?
To convert feet per second (fps) to joules, you need the mass of the projectile. The formula to calculate joules is 0.5 * mass * velocity^2. Without knowing the mass of the projectile, it is not possible to accurately calculate joules based solely on the velocity of 300 fps.
A student does 300 joules of work pushing a cart 3 meters due east then does 400 joules of work pushing the cart 4 meters due north the total amount of work done by the student is what?
700 joules
If It takes 300 N to move a box 10 meters in 10 seconds How much power is required?
The total work done or energy transferred is equal to the product of the force and the displacement in the direction of the force applied. In this case it would be 300N x 10m to get 3000J. This energy is transferred in 10 seconds and since power is energy transferred per unit time... 3000J divided by 10 seconds equals 300 Watts or 300 Joules per second.
