Answer:

F=m*g is the formula and the answer is 19,620 kg

Explanation:

Since the formula is F=m*g and Earth's gravity is 9.81 m/s^2 all you need to do is multiply 2,000 by 9.81

Answer:

$20,000\:\mathrm{N}$

Explanation:

The weight of an object on Earth is equal to the force of gravity on that object.

We can use the following equation to determine the force of gravity on an object:

$F_g=ma_g=mg$ , where $m$ is the mass of the object and $g$ is acceleration due to gravity ( $9.81\: \mathrm{m/s}$ ).

Solving, we get: $F_g=2,000\cdot9.81=19,620=\fbox{$20,000\:\mathrm{N}$}$ (one significant figure).

There are two torques t1 and t2 on the beam due to the weights, one torque t3 due to the weight of the beam, and one torque t4 due to the string.

You need to figure out t4 to know the tension in the string.

Since the whole thing is not moving t1 + t2 + t3 = t4.

torque t = r * F * sinФ = distance from axis of rotation * force * sin (∡ between r and F)

t1 =3.2 * 44g
t2 = 7 * 49g
t3 = 3.5 * 24g

t4 = t1 + t2 + t3 = 5570,118

The t4 also is given by:

t4 = r * T * sin Ф

r = 7
Ф = 32°
T: tension in the string

T = t4 / (r * sinФ)

T = t4 / (7 * sin(32°))

T = 1501,6 N

Sketch a reaction progress curve for a reaction that has an activation energy of 22 kj and the total energy change is -103kj.

crimeas [40]

Answer:

Do find the answer in the attachment herein.

Explanation:

From the attached diagram:

I. Activation energy = Activated complex - ∆H(reactants)

Activation energy = 162-140 = 22Kj.

II. ∆H(reaction) = ∆H(products) - ∆H(reactants)

∆H(reaction) = 37 - 140 = -103Kj.
