A sled of mass 15 kg slides across the ground with a friction force of 80.85 N. What is k between the sled and the ground?

Dvinal [7]

The expression for the frictional force between the sled and the ground is:
$F=k m g$
where $k$ is the coefficient of friction, m is the mass of the object and $g=9.81 m/s^2$ is the gravitational acceleration.

The friction force in our problem is F=80.85 N. The mass of the object is m=15 kg. Re-arranging the formula, we can find the value of k:
$k= \frac{F}{mg}= \frac{80.85 N}{(15 kg)(9.81 m/s^2)}=0.55$

Here Are Some Tanning Bed Tips For Beginners To Help You Get The Most .Knowing your skin type before you tan can help you to do so safely and help . If you want to ensure you get a quality tan, you first need to be certain your . Obviously, if you wear a bathing suit, you'll get tan lines from the suit. Apply indoor tanning lotion evenly in a circular motion and over all areas of the body. Using the right skin care products is the best way to extend the life of your tan. Note that lotions not made for indoor tanning can cause damage to tanning beds and don't help develop your tan. So what (if anything) should you wear? There are a lot of different views on this particular question, and it all comes down to one very simple answer: wear whatever you are comfortable in. If you wear your bathing suit every time, you will have tan lines that reflect that, but that's your choice.

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.

A 15-µF capacitor is charged to 40 V and then connected across an initially uncharged 25-µF capacitor. What is the final potenti

Kobotan [32]

Answer:

24volts

Explanation:

If a 15-µF capacitor is charged to 40V, the charge across the capacitor can be calculated using the formula;

Q = CV where;

Q is the charge flowing across the capacitor

C is the capacitance of the capacitor. = 15-µF

V is the voltage = 40V

Q = 15×10^-6×40

Q = 0.0006coulombs

If the charge of 0.0006coulombs is then connected across an initially uncharged 25-µF capacitor, the potential difference across the 25-µF can be calculated using the initial expression;

Q = CV

V = Q/C

V = 0.0006/25×10^-6

V = 24Volts

Therefore, the final potential difference across the 25-µF capacitor will be 24volts

Which of the following electromagnetic waves carries the highest

Harman [31]

Complete Question:

Which of the following electromagnetic waves carries the highest energy, and are most damaging to human?

A. Gamma Rays

B. Microwave

C. Radio-wave

D. Alpha Rays

Correct Option:

Gamma Rays carries the highest energy, and are most damaging to human.

Option: A

Explanation:

The waves of light and other forms of energy that radiate or travel from where they are originated is understood as electromagnetic radiation, and collectively represent electromagnetic spectrum. The gamma rays are dangerous sources of radiation with high energy. Its standard size is 0.000001 nm i.e. size of atomic nucleus diameter. It results from the degradation of atomic nuclei by radioactive means. It is made up of the smallest electromagnetic wavelength, and thus provides the highest photon energy.
