If a 10,000 g mass is suspended from a rope, what is the tensile force in the rope?

nadezda [96]

To solve this problem we will apply Newton's second law and the principle of balancing Forces on the rope. Newton's second law allows us to define the weight of the mass, through the function

$F = ma\rightarrow F =mg$

Here,

m = mass

a = g = Gravitational acceleration

Replacing we have that the weight is

$W= (10kg)(9.8)$

$W = 98N$

Since the rope is taut and does not break, the net force on the rope will be zero.

$\sum F = 0$

$T-W = 0$

$T = W$

$T = 98N$

Therefore the tensile force in the rope is 98N

Why is photosynthesis important to cellular respiration?

Mnenie [13.5K]

Photosynthesis's products are the reactants for cellular respiration. Photosynthesis equation: 6CO2 + 6H2O+ light ->C6H12O6 + 6O2. Then basically swap it and instead of light out in energy: C6H12O6 + 6O2 -> 6CO2 + 6H2O + Energy. Hope this helps!

Find the volume for 30 points.

Nina [5.8K]

Answer:

336.78 cubic feet

Explanation:

total volume= volume of cuboid + volume of cylinder

= lxbxh + π r^2h

= 9x7x4 + 3.14x(3)^2 x3

= 252+ 84.78

= 336.78 cubic feet

A toy car of mass 8 kg initially moves with a speed of 5 m/s. How much work must be done on the car to increase its speed to 10

sukhopar [10]

ANSWER:

300 J

STEP-BY-STEP EXPLANATION:

To know the work required, we must calculate the work in both cases, the difference would be the amount of work necessary for the speed to increase. The work done is the same as the amount of energy increase. The formula for kinetic energy is:

$\frac{1}{2}m\cdot v^2$

We calculate in each case:

$\begin{gathered} \frac{1}{2}\cdot8\cdot10^2=400\text{ J} \\ \frac{1}{2}\cdot8\cdot5^2=100\text{ J} \end{gathered}$

We calculate the difference between the two to find out the work required:

$400-100=300\text{ J}$

The work required is 300 J
