Answer:

Yes it is related

Explanation:

Consider 2 points in a rectangular co-ordinate system

(x_{1},y_{1}),(x_{2},y_{2})

The distance between them can be found by

d = \sqrt{(x_{1}-x_{2})^{2}-(y_{2}-y_{1})^{^{2}}}

This is clear from the figure attached below

27 degrees to kelvin, 20 dg to milligrams, and 3 to decimeters.
Gala2k [10]
K = C + 273, so 27°C = 27+273 = 300 K

1 dg = 100 mg, so 20 dg = 20×100 = 2,000 mg

One end of a 34-m unstretchable rope is tied to a tree; the other end is tied to a car stuck in the mud. The motorist pulls side
anyanavicka [17]

Answer:

Fc = 89.67N

Explanation:

Since the rope is unstretchable, the total length will always be 34m.

From the attached diagram, you can see that we can calculate the new separation distance from the tree and the stucked car H as follows:

L1+L2=34m

L1^2=L2^2=L^2=2^2+(H/2)^2  Replacing this value in the previous equation:

\sqrt{2^2+H^2/4}+ \sqrt{2^2+H^2/4}=34  Solving for H:

H=\sqrt{52}

We can now, calculate the angle between L1 and the 2m segment:

\alpha = atan(\frac{H/2}{2})=60.98°

If we make a sum of forces in the midpoint of the rope we get:

-2*T*cos(\alpha ) + F = 0  where T is the tension on the rope and F is the exerted force of 87N.

Solving for T, we get the tension on the rope which is equal to the force exerted on the car:

T=Fc=\frac{F}{2*cos(\alpha) } = 89.67N

Xelga [282]

Answer: Because of the reflects back into space equal amount of radiation as it receives.

Explanation: The Earth's temperature doesn't keep rising because as the Earth receives the radiation from the sun, the Earth reflects back an equal amount of that radiation back to space.

This reflective ability of a planet of the sun radiation incident on it is known as the albedo.

A hockey player uses her hockey stick to exert a force of 7.957.95 N on a stationary hockey puck, which is resting on a nearly f
Firlakuza [10]

Answer:

44 m/s^2

Explanation:

Force, F = 7.95 N

mass, m = 181 g = 0.181 kg

By use of Newton's second law

F = m x a

a = F / m = 7.95 / 0.181 = 44 m/s^2

Thus, the acceleration of the hockey puck is 44 m/s^2.
