It is 5.0 km from your home to the physics lab. As part of your physical fitness program, you could run that distance at 10 km/h
Ostrovityanka [42]

Answer:

Walking burns up more energy,1740000J

Explanation:

Given that the displacement is 5.0km, and running at 10km/h and uses, walking at 3km/hr and uses 290watts:

Energy consumption for running is calculated as:

700watts=700j/s,d=5000m,v=\frac{25}{9}m/s\\\\\therefore E_c=\frac{d}{v}\times Energy \ usage\\\\=\frac{5000}{\frac{25}{9}}\times 700j/s\\\\=1260000J

Energy consumption for walking is calculated as:

290watts=290j/s,d=5000m,v=\frac{5}{6}m/s\\\\\therefore E_c=\frac{d}{v}\times Energy \ usage\\\\=\frac{5000}{\frac{5}{6}}\times 290j/s\\\\=1740000J

Walking is a slower process hence the need for more energy over longer periods  raltive to running the same distance.

Hence walking burns more energy; 1,740,000J. It burns more because you walk for a greater period of time.

An 8 Ω resistor is connected to a battery. The current that flows in the circuit is 2 A. Calculate the voltage of the battery.
Crank

Here is the highly detailed, arcane, complex, technical form of Ohm's Law that is needed in order to answer this question  ===> V = I · R .

Voltage = (current) x (resistance)

Voltage = (2 Ampere) x (8 Ω)

<em>Voltage = 16 volts</em>

two coins lie 1.5 meters apart on a table. they carry identical electric charges. approximately how largeis the charge on each c
BARSIC [14]

The charge on each coin is equal to

Given the following data:

Force = 2.0 Newton

Radius = 1.5 meters

To determine the charge on each coin, we would apply the law of electrostatic forces:

Mathematically, the law of electrostatic forces is given by the formula:

Note:  (since the coin carry identical electric charges).

Therefore, the formula becomes:

Making q the subject of formula, we have:

Substituting the given parameters into the formula, we have;
