Answer:

The rule to remember is that opposites attract. Every magnet has both a north and a south pole. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.

Magnets are attracted when the opposite side is facing eachother, but they repel once the same side is facing eachother.

what is the average acceleration of a four wheeler that speeds up from 3 miles per hour to 15 miles per hour in 0.6 hours
den301095 [7]
A= change in velocity / change in time

a  =  \frac{change \: in \: velocity}{change \: in \: time}
a =  \frac{15 - 3}{0.6}
a = 20 \:  \frac{m}{ {s}^{2} }

A racecar traveling at a velocity of 18.5 m/s, accelerates at a rate of 2.47 m/s2 and covers a distance of 79.78 m. Determine th
Vesna [10]

Answer:

The final velocity of the race car is 27.14 m/s

Explanation:

Given;

initial velocity of the race car, u = 18.5 m/s

acceleration of the race car, a = 2.47 m/s²

distance covered by the race car, s = 79.78 m

Apply the following kinematic equation to determine the final velocity of the race car.

v² = u² + 2as

v² = (18.5)² + 2(2.47)(79.78)

v² = 736.363

v = √736.363

v = 27.14 m/s

Therefore, the final velocity of the racecar is 27.14 m/s

A person is standing on a level floor. His head, upper
BabaBlast [244]

Answer:

y_{cg} = 1.03 m

Explanation:

Given data:

weigh (head+arms + head) w_1 = 438 N

centre of gravity y_1= 1.28 m

weigh (upper leg) w_2 = 144 N

Center of gravity y_2 = 0.760 m

weigh ( lower leg + feet) = 87 N

centre of gravity = y_3 = 0.250 m

location of center of gravity = \frac{w_1 y_1 + w_2 y_2 + w_3 y_3}{w_1 +W_2 +w_3}

y_{cg} = \frac{438 \times 1.28 + 144\times 0.760 + 87 \times 0.250}{438+144+87}

y_{cg} = 1.03 m
