Answer:
28852 J
Explanation:
When a force applied in a body produces a displacement in it, the force realized a work. The force that moves Karen is contrary to her weight and must be equal to it.
The work (W) is:
W = F.d.cos(θ), where F is the force, d is the displacement, and θ is the angle.
Knowing that cos(26°) = 0.899, and F = m*g
W = 51.9*9.8*63.1*0.899
W = 28852 J
In space, spatial coordinates can be roughly divided into measures of Right ascension and declination. The declination is measured in degrees while the ascent is measured in hours, minutes, seconds. When you have objects in space such as those of the characteristics presented we will have to they are not necessarily close together in the sky because we can find two stars on the same right ascension but on different declination lines (Which means they can be very far apart from each other)
The answer to the given question above is option C. In a classical conditioning experiment, you ring a bell but no longer provide dinner to your subject, a beagle and at last, the CS no longer evokes the CR so therefore, <span> you've accomplished behavioral EXTINCTION. Hope this helps.</span>
Answer:
D or A ( I think)
Explanation:
Cause you know how people say the smaller the chips the more the chips its kind of the same with amplitude.
( hope it helps if I am wrong I am sorry)
Options A and C are correct but if you compare their masses, person has negligible mass compared to car. So a car at the top of the hill has the most potential energy.
