The total mass of the wheelbarrow and the road is 80 kg calculate the weight of the wheelbarrow and the road

Physics
1 answer:
Alja [10]3 years ago
7 0

Answer:

The weight of the wheelbarrow and the road is 784 N and the force required to lift the wheelbarrow is 784 N.

Explanation:

Given that,

The total mass of the wheelbarrow and the road is 80 kg.

The weight of an object is given by :

W = mg

where

g is acceleration due to gravity

So,

W = 80 × 9.8

= 784 N

So, the force required to lift the wheelbarrow is equal to its weight i.e. 784 N.

wlad13 [49]

Answer:

average speed  is 0.159 m/s

average velocity = 0.0011 m/s

Explanation:

given data

time = 41.6 s

total distance = 6.65 m

length = 0.0463 m

to find out

average speed and the magnitude average velocity

solution

we know average speed formula is

average speed = \frac{total distance}{total time}   ...............1

put here value

average speed = \frac{6.65}{41.6}

average speed  is 0.159 m/s

and

average velocity formula is

average velocity = \frac{displacement}{total time}   ...............2

here displacement is initial point to final point and here is 0.0463 m

put here value

average velocity = \frac{0.0463}{41.6}

average velocity = 0.0011 m/s

What is the temperature if the peak of a blackbody spectrum is at 18-nm?
finlep [7]

Answer:

Explanation:

According to Wein's displacement law

\lambda_{max} T = b

Where b = 2.898 x 10⁻³ m K

Given ,

\lambda{max} = 18\times10^{-9}

T = 161 X 10³ K.

How can a bulb be resistor?​
valkas [14]

Answer: The reason a light bulb glows is that electricity is forced through tungsten, which is a resistor. The energy is released as light and heat. A conductor is the opposite of a resistor. Electricity travels easily and efficiently through a conductor, with almost no other energy released as it passes.

Why cant your rocket could never reach the speed of light?
Oksanka [162]

Answer:

The length of the object would shrink to zero which is not possible.

Explanation:

A rocket or any body cannot reach the speed of light because according to theory of relativity the and the Lorentz factor the length of the object would shrink to zero and the time dilation for that body would be infinite.

The Lorentz factor is given as:

\gamma=\frac{1}{\sqrt{\frac{v^2}{c^2} } }

where:

v = speed of the moving object

c = speed of light
