Answer:
<em>The horizontal component of the velocity is 49.85 m/s.</em>
Explanation:
<u>Rectangular Components of a Vector</u>
A 2D vector can be expressed in several forms. The rectangular form gives its two components, one for each axis (x,y). The polar form gives the components as the pair (r,θ) being r the magnitude and θ the angle.
When the magnitude and angle of the vector are given, the rectangular components are calculated as follows:
Where v is the magnitude of the vector and θ is the angle with respect to the x positive direction.
The cart is moving at v=55 m/s at θ=25°, thus:
The horizontal component of the velocity is 49.85 m/s.
I looked up the question and got D- a vacuum
Einstein's theory of General Relativity states that space-time is able to be warped in the presence of mass or energy. This warping is what "tells" matter how to move in its presence. In the paraphrased words of physicist John Wheeler, matter tells space-time how to warp, and warped space-time tells matter how to move.

Answer: 0.42 watts
Explanation:
Given that:
power = ?
energy =500 joules
time = 1200 seconds
Recall that power is the rate of energy expended per unit time
i.e Power = energy / time
Power = 500J / 1200seconds
Power = 0.416 watts (rounded to the nearest hundredth as 0.42 watts)
Thus, the power of the instrument is 0.42 watts
