How much work is done on a pumpkin with a force of 16 newtons when you lift it 15<br> meters?

blsea [12.9K]

Answer:

240 Joules

Explanation:

work = f x d

16 newtons is the force

15 meters is the distance

When the starter motor on a car is engaged, there is a 300 A cunent in the wires between the bauery and the motor. Suppose the w

docker41 [41]

Answer:

diameter of transmission is 3.473 mm

Explanation:

given data

current = 300 A

total wire length = 1.0 m

voltage drop = 0.55 V

solution

as here Resistivity of copper is = 1.68 × $10^{-8}$ ohm- m

so we get here resistance of wire that is

resistance = $\frac{V}{I}$ ..............1

R = $\frac{0.55}{310}$

R = 1.774 × $10^{-3}$ ohm

and now we get diameter of wire that is

R = $\frac{\rho l}{A}$ .............2

$\pi \frac{d^2}{4} = \frac{\rho l}{R}$

d² = $\frac{4\rho l}{\pi R}$ ...............3

put here value

d² = $\frac{4\times 1.68\times 10^{-8} \times 1}{\pi \times 1.774\times 10^{-3}}$

d = $\sqrt{12.064\times 10^{-6}}$

d = 3.473 × $10^{-3}$ m

d = 3.473 mm

so diameter of transmission is 3.473 mm

A block with a weight of 3.0 N is at rest on a horizontal surface.A 1.0 N upward force is applied to the block by means of an at

Genrish500 [490]

Answer:

Explanation:

Given

weight of block $W=3\ N$

A force is of $F=1 N$ is applied on the block

As 1 N is less than weight of block so block exert Force less than its weight

$F_{net}=mg-F$

$F_{net}=3-1=2\ N$

So Block exert a force of 2 N downward on floor

Two uncharged metal spheres, #1 and #2, are mounted on insulating support rods. A third metal sphere, carrying a positive charge

tatuchka [14]

Answer:

The question is incomplete as some details are missing, here is the details ;

In this final state

a) spheres #1 and #2 both carry negative charge.

b) sphere #1 carries negative charge and #2 carries positive charge.

c) spheres #1 and #2 are still uncharged.

d) sphere #1 carries positive charge and #2 carries negative charge.

e) spheres #1 and #2 both carry positive charge.

Explanation:

From the concept of electrostatics, if a positively charged sphere is brought close to #2, there will be attraction of the opposite charges(-ve) towards it.

Now connecting a copper wire between #1 and #2, opposite charges will flow from #1 towards #2. disconnecting the copper wire makes #1 to be positively charged and #2 to be negatively charge and from the laws of attraction ; Like charges repel and unlike charges attract. the correct option is d.
