What makes up the unit joules?​

Physics

Joule. Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds

One joule is defined as the amount of energy exerted when a force of one newton is applied over a displacement of one meter. One joule is the equivalent of one watt of power radiated or dissipated for one second. In some applications, the British thermal unit (Btu) is used to express energy.

The joule has base units of kg·m²/s² = N·m. A joule is defined as the work done or energy required to exert a force of one newton for a distance of one metre

n equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph. In practical terms, even a small force can do a lot of work if it is exerted over a long distance.

Multiply watts by seconds to get joules.

A 1 Watt device consumes 1 Joule of energy every 1 second. If you multiply the number of watts by the number of seconds, you'll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules.

Answer:

1) Energy transfer is the movement of energy from one location to another. ... Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.

2)A swinging pirate ship ride at a theme park. Kinetic energy is transferred into gravitational potential energy.

Bringing water to the boil in an electric kettle.

3)Common examples of energy storage are the rechargeable battery, which stores chemical energy readily convertible to electricity to operate a mobile phone, the hydroelectric dam, which stores energy in a reservoir as gravitational potential energy, and ice storage tanks, which store ice frozen by cheaper energy at night

What is happening if energy input remains constant and voltage remains the same in a circuit, but the current decreases?
guajiro [1.7K]
<span>A. The resistance has increased. Because here current is decreasing. Option C is incorrect cuz Power will decrease as resistance decreases according to equation P= v^2/R. V = volts, R = resistance. Hope it helps</span>

The heavyweight boxing champion of the world punches a sheet of paper in midair, bringing it from rest up to a speed of 26.5 m/s
enyata [817]

corrected question:The heavyweight boxing champion of the world punches a sheet of paper in midair, bringing it from rest up to a speed of 26.5 m/s in 0.044 s . The mass of the paper is 0.003 kg. Part A Find the force of the punch on the paper

Answer:

Force=1.8N

Explanation:

Newtons third law states that in every action there is equal and opposite reaction.

The force of the punch will be the force that moves the paper by a speed of 26.5m/s.

F=ma

F=m\frac{v-u}{t}

m=0.003kg , v=26.5m/s  u=0(the paper is punched from rest) t=0.044s

F=0.003*\frac{26.5-0.044}{0.044}

F=1.8N

assuming that voltage remains constant, what happpens to the current in a wire as its diameter decreases?
Nataly_w [17]
A larger diameter wire has lower resistance. A lower resistance wire produces less heat for a given current flowing through it.
