The skateboarder will have the greatest potential energy at point <em>G.</em>

Potential energy is the energy possessed by a body by virtue of its position. The gravitational potential energy of a body is given by the expression,

$E_P=mgh$

Here, <em>m</em> is the mass of the body, <em>g</em> the acceleration due to gravity and <em>h</em> is the height of the body from the ground.Thus as <em>h</em> increases, the potential energy increases.

From the figure, it can be seen that the highest point in the skateboarder's trajectory is <em>G.</em> hence, he would have the highest potential energy at the point <em>G.</em>

If a bicyclist, with initial velocity of zero, steadily gained speed until reaching a final velocity of 26m/s, how far would she

svetlana [45]

Answer:

34.45m

Explanation:

Using the equation of motion formula v² = u²+2as to get the distance travelled

v is the final velocity = 26m/s

u is the initial velocity = 0m/s

a is the acceleration due to gravity = 9.81m/s²

S is the distance travelled

Substituting the given values into the formula;

26² = 0²+2(9.81)s

676 = 0 + 19.62s

19.62s = 676

s = 676/19.62

s = 34.45m

Hence the distance she would travel during the race is 34.45m

True or false: Decreased output from the vasomotor center allows arterioles and veins to constrict.

wolverine [178]

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

The above statement is False

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

Decreased output from the vasomotor center allows arterioles and veins to dilate.
The vasomotor center controls vessel tone or contraction of the smooth muscle in the tunica media.It is responsible for central regulation of cardiac electrical activity, myocardial performance, and peripheral vascular tone.
Changes in diameter affect peripheral resistance, pressure, and flow, which in turn affect cardiac output.

What is the force when an object exerts 15 pascal pressure on a square surface of side 5 meters

olga55 [171]

Answer:375N

Explanation:

pressure =15 pascal

Length of side =5 m

Area=length x length

Area=5 x 5

Area=25 m^2

Force=pressure x area

Force=15 x 25

Force=375N
