<h3><u>Answer;</u></h3>

= 2868 Newtons

<h3><u>Explanation;</u></h3>

Centripetal force is a force that acts on an object or a body in circular path and is directed towards the center of the circular path.

Centripetal force is given by the formula;

mv²/r ; where m is the mass of the body, r is the radius of the circular path and v is the velocity of a body;

mass = 65 kg, velocity = 15 m/s and r = 5.1 m

Therefore;

Centripetal force = (65 × 15²)/ 5.10

                            = 2867.65 Newtons

                            = 2868 N

gayaneshka [121]

Answer:

The value is E =  1.35 *10^{14} \ J

Explanation:

From the question we are told that

    The mass of matter converted to energy on first test is  m  =  1 \  g  = 0.001 \  kg

    The mass of matter converted to energy on second test m_1 =  1.5 \  g = 1.5 *10^{-3} \ kg

    Generally the amount of energy that was released by  the explosion is  mathematically  represented as  

         E =  m * c^2

=>       E =  1.5 *10^{-3}  * [ 3.0 *10^{8}]^2

=>       E =  1.35 *10^{14} \ J

Which equation would you use to solve the following problem? An object is moved 29 m with a force of 289 N. What is the work don
Ksivusya [100]
Work, scientifically speaking, is done when a force is applied to an object which consequently moves the object at a certain direction. Work in formula, is force multiplied with distance.
 W = F x d

Issac newton how did he shape the new worldview?
gulaghasi [49]

Accordingly Newton's findings, astronomy and physics have industrialized hugely over the period.  Scientists now recognize that every object in the world has a force that draws each other and the power of the force hinge on the mass of the object.  Also, Newton's Laws of Motion offer individuals a better understanding of what is likely concerning movement.  This is very helpful, particularly in  mechanics and space travel.  Generally, Newton had a huge and permanent impact on science.
