Answer:

98 kg

Mass is given as 10 kg. Therefore, Weight = 10 kg * 9.8 m/s^2. Weight = 98 kg.m/s^2. = 98 Newtons.

The weight in newtons of a 10 kg mass on the earth's  surface is 98 N.

<u>Explanation:</u>

Every object on the Earth experiences an acceleration of 9.8 m/s^2 due to gravity. From the given,

Mass of the object = 10 kg

To calculate the weight of the object we have to multiply the given mass of the object by the acceleration due to gravity.

i.e. Weight= Mass\times Acceleration \ due \ to \ gravity

Acceleration due to gravity = 9.8 m/s^2

On substituting the values,

Weight = 10 kg\times 9.8 m/s^2

(1 N = 1 kg. m/s^2)

\bold{\Rightarrow 98 \ kg.m/s^2\Rightarrow 98 N}

Weight = 98 N

How far will you travel if you run for 10. minutes at 2.0 m/s?
oee [108]
We know that 1 minute= 60 seconds (or 1 min= 60 s).

10 min* (60 s/ 1 min)* (2.0 m/ 1 s)= 1,200 m.
(Note that the units cancel out so you get the answer)

The final answer is 1,200 m.

Hope this helps~

If a nearsighted person has a far point df that is 3.50 m from the eye, what is the focal length f1 of the contact lenses that t
Anastaziya [24]

Answer:

f1 = -3.50 m

Explanation:

For a nearsighted person an object at infinity must be made to  appear  to be at his far point which is 3.50 m away. The image of an object at infinity must be formed on the same side of the lens as the object.

∴ v = -3.5 m

Using mirror formula,

i/f1 = 1/v + 1/u

Where f1 = focal length of the contact lens, v = image distance = -3.5 m, u =         object distance = at infinity(∞) = 1/0

∴ 1/f1 = (1/-3.5) + 1/infinity

  Note that, 1/infinity = 1/(1/0) = 0/1 =0.

∴ 1/f1 = 1/(-3.5) + 0

  1/f1 = 1/(-3.5)

Solving the equation by finding the inverse of both side of the equation.

∴ f1 = -3.50 m

 Therefore a converging lens of focal length  f1 = -3.50 m

would be needed by the person to see an object at infinity clearly
