avanturin [10]3 years ago
3 0

Answer:

Explanation:

As the sum of the two right directed forces match exactly the left directed force, the only unbalanced force, and thus the net force, is the upward 25 N force.

What is a reasonable estimate of the average kinetic energy of an athlete during a 100 m race that takes 10s?
arlik [135]
The average weight of an athlete should be around 60kg so from the information that the athlete can run 100m in 10s, we can calculate that their average speed is 10m/s. Using the kinetic energy formula, Ek = 1/2mv^2 we can calculate the kinetic energy using 60kg as the mass.

(1/2)(60)(10^2) = Ek

Ek= 3000J

A vertical straight wire carrying an upward 28-A current exerts an attractive force per unit length of 7.83 X 10 N/m on a second
JulijaS [17]

Answer:

i_2 = 978750 A

Since the force between wires is attraction type of force so current must be flowing in upward direction

Explanation:

Force per unit length between two current carrying wires is given by the formula

F = \frac{\mu_0 i_1 i_2}{2 \pi d}

here we know that

F = 7.83 \times 10 N/m

d = 7.0 cm = 0.07 m

i_1 = 28 A

now we will have

F = \frac{4\pi \times 10^{-7} (28.0)(i_2)}{2\pi (0.07)}

7.83 \times 10 = \frac{2\times 10^{-7} (28 A)(i_2)}{0.07}

i_2 = 978750 A

Since the force between wires is attraction type of force so current must be flowing in upward direction

A cart was allowed to roll down a ramp from rest. It reached the bottom of the ramp with a speed of 25 cm/s. A student could con
ladessa [460]

Answer:

A student could conclude that the cart gained momentum as it rolled down.

Explanation:

If the cart was allowed to roll down the ramp from rest, it means that the initial velocity of the cart is zero (0). Also, if the final velocity of the cart became 25 cm/s, it means that the velocity of the cart increased from 0 to 25 cm/s.

Therefore, A student could conclude that the cart gained momentum as it rolled down.

four objects are situated along the y axis as follows: a 2.00kg object is at +3.00m. a 3.00kg object is at +2.50m, a 2.50kg obje
Mashutka [201]

The centre of mass of the objects is (0,1)m .

What do you mean by Centre of mass?

The centre of mass is a position defined relative to an object or system of objects .

We have given

m1=2kg , y1= 3

m2= 3kg ,y2=2.5m

m3=2.5kg ,y3= 0m

m4=4kg , y4= -0.5m

Ycm=mixi/mi

→2×3+3×2.5+2.5×0+4×0.5/4.5

→1m

Centre of mass of these object is at (0,1)m .
