A 50.0-kg block is being pulled up a 13.0° slope by a force of 250 N which is parallel to the slope, but the block does not slid
Elan Coil [88]

<span>Weight of block, Wb = mass*gravity = 50*9.8 = 490 N</span>

Since block is being pulled up by a 13-degree slope

Therefore, Force which is acting parallel to the slop:

<span> F p =490 Sin </span>13^{0}= 110.2N

Force which is acting perpendicular to the slope:

<span> Fv =490 Cos</span>13^{0} = 477.4 N

Net force can be given as follows:

<span>F n = (250 - 110.2 - 0.2*</span>477.4) N

<span>Fn=44.3N</span>

Now acceleration is given by the ratio of force to mass

<span>a = Fn/m</span>

<span>=44.3/50 = 0.89 ms^<span>-2</span></span>

What is the difference between centrifugal force and centripetal force???
topjm [15]
Centripetal force is defined as, "the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation," while centrifugal force is defined as "the apparent force that is felt by an object moving in a curved path that acts outwardly away from the center of rotation," according to Merriam Webster Dictionary.

Hedea made a study chart about nuclear energy. Which best describes the error in Hedea’s chart? The nuclei of atoms are split ap
Lerok [7]

Option (d) is correct.Fission and fusion convert nuclear energy to both radiant and thermal energy.

fission is a process in which bigger nucleus breaks into two or more smaller nuclei with the liberation of a large amount of energy.

Fusion is a process in which two small nuclei fuse together to from an intermediate size nucleus with the liberation of tremendous amount of energy

During fission and fusion, energy is released in the form of both light (radiation) and heat.we can then convert that energy into useful form.
