Answer:

25 kg

Explanation:

Given,

Acceleration ( a ) = 2 m/s^2

Force ( F ) = 50 N

To find : Mass ( m ) = ?

Formula : -

F = ma

m = F / a

= 50 / 2

m = 25 kg

So, the mass of the body is 25 kg.

Use the formula force = mass x acceleration

Your force = 50 Newton’s and your acceleration = 2 meters per second
So the equation should look like this

A girl and a boy pull in opposite directions on strings attached to each end of a spring balance. Each child exerts a force of 2
BabaBlast [244]

Answer:

yo they deleted my answer. The answer is 0N

Explanation:

so when two forces pull on an object from opposite sides with the same force (in this case its 20N), then the object is in equilibrium at 0N.

So its clear that there is one person on the the opposite side.

SOOO  generally<u>: (left or down) would be considered </u><u>negative</u><u> in an equation. And the other person  (right or up) would be considered </u><u>positive</u><u>.</u> So if both forces are the same numbers on opposite sides then the answer is 0 (if you add both of them).

<em>0 is the number of equilibrium.</em>

OK, so the equation would be -20N + 20N and then badda bing badda boom viola, the answer: 0N

thanks for coming to my TED talk. I hope they don't delete this answer.

You are standing on a footbridge that is 12 feet above a lake. You look down and see a duck in the water. The duck is 7 feet awa
kolbaska11 [484]

Answer:

  30.22°.          

Explanation:

Given that

height of the bridge ,h= 12 ft

The distance of the lake from bridge ,L= 7 m

 Lets take angle = θ

Now by using diagram

We can say that

tan\theta =\dfrac{L}{h}

tan\theta =\dfrac{7}{12}

tan\theta=0.583

\theta=30.22^{\circ}

That is why the angle will be 30.22°.

A CD has a diameter of 12.0 cm. If the CD is rotating at a constant angular speed of 200 revolutions per minute, then the tangen
ozzi

Hi there!

Converting from angular velocity to tangential velocity can be done by:

v = ωr

v = tangential velocity (m/s)

ω = angular velocity (rad/sec)

r = radius (m)

Convert 12 cm to meters:

100 cm = 1 m

12 cm = 0.12 m

Now, convert rev/min to rad/sec:

{\frac{200rev}{min}} * \frac{1min}{60s} * \frac{2\pi rad}{1 rev} = 20.94 rad/sec

v = 20.94 · 0.12 = 2.51 m/s

Which of the following is true about free energy? A. It is all the energy that a molecule contains B. The free energy change of
son4ous [18]

Free energy is a thermodynamic potential that can be used to calculate the maximum reversible work that can be performed by a thermodynamic system at a constant temperature and pressure. It is fulfilled that if the energy change is less than zero it will mean that the relationship will proceed towards the product, while if the relationship is greater than zero the reaction will proceed towards the reactant. Therefore the correct option is D.

<em>The free energy change of a reaction can determine the reaction direction</em>
