A 45.0 kg student runs at a constant velocity up the incline 6 metres high. If the power output of the student is 1.50 x 103 W,

serg [7]

Answer:

The time taken is 1.76 s.

Explanation:

mass of student, m = 45 kg

height, h = 6 m

power, P = 1500 W

Power is defined as the rate of doing work.

Work done in moving height is

W = m g h

Let the time is t.

P = m g h / t

1500 = 45 x 9.8 x 6 / t

t = 1.76 s

An unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only

vlabodo [156]

Answer:

15.8m/s

Explanation:

This problem can be solved by taking into account the conservation of the momentum. In this case the momentum of the astronaut and the bag of tools must equal the momentum of the astronaut and the bag of tool after the astronaut throws the bag.

Hence, we have

$p_{before}=p_{after}\\(m_{a}+m_{b})v=m_{a}v_{a}+m_{b}v_{b}$

where ma and va are the mass and velocity of the astronaut, mb and vb are the mass and velocity of the bag, after the astronaut throw the bag. The velocity v is the velocity where the astronaut has the bag of tool

By taking into account that the velocity of the astronaut must be zero to keep him near of the space station, we have that vb = 0.

Thus

$(124 + 19.0)2.10=19.0v_{b}\\v_{b}=\frac{300.3}{19.0}=15.8m/s$

Help pls i need this right now

BabaBlast [244]

Answer:

C = - 1.625 i + 6.06 j

Explanation:

Positive angles are measured counterclockwise.

Positive angles are measured counterclockwise. To determine the component on the x axis we use the cosine of the angle while to determine the component on the y axis we use the sine of the angle.

$C_{x}=6.28*cos(105)=-1.625\\C_{y}=6.28*sin(105)=6.06\\$

C = - 1.625 i + 6.06 j

Early mapmakers thought continents might have moved based on their observation of

Elodia [21]

Answer:

C. matching coastlines

Explanation:

The theory of continental drift was originally proposed in 1912 by German meteorologist and geophysicist Alfred Wegener (1880-1930), who formulated it based, among other things, on how they seemed to fit the shapes of the continents on each side of the Atlantic Ocean, such as Africa and South America. This had previously been speculated by some mapmakers.
