Answer:

6.53 m/s²

Explanation:

Let m₁ = 5 kg and m₂ = 10 kg. The figure is attached and free body diagrams of the objects are also attached.

Both objects (m₁ and m₂) have the same magnitude of acceleration(a). Let g be the acceleration due to gravity = 9.8 m/s². Hence:

T = m₁a               (1)

m₂g - T = m₂a    (2)

substituting T = m₁a in equation 2:

m₂g - m₁a = m₂a

m₂a + m₁a = m₂g

a(m₁ + m₂) = m₂g

a = m₂g / (m₁ + m₂)

a = (10 kg * 9.8 m/s²) / (10 kg + 5 kg) = 6.53 m/s²

Both objects have an acceleration of 6.53 m/s²

What is the mass of 3.70 L of water? Remember 1000 L = 1 m^3 (Unit=Kg)
xxMikexx [17]

Answer:

3.7kg

Explanation:

The following data were obtained from the question:

Volume = 3.7L

Mass =?

Next, we shall convert 3.7L to m³.

This is illustrated below:

1000L = 1m³

Therefore, 3.7L = 3.7/1000 = 0.0037m³

Now, we can obtain the mass of the water as shown below:

Density of water = 1000kg/m³

Volume of water = 0.0037m³

Mass of water =..?

Density = Mass /volume

1000kg/m³ = Mass /0.0037m³

Cross multiply

Mass = 1000Kg/m³ × 0.0037m³

Mass = 3.7Kg

Therefore, the mass of the water is 3.7Kg.

If f(x) = -3x +4 and g(x) = 2, solve for the value of x for<br>which (fx) = g(x) is true.​
maksim [4K]

Answer:

x=-\frac{2}{3}

Explanation:

Let:

f(x)=-3x+4\\\\And\\\\g(x)=2

We need to know for which value of x the function f(x) is equal to g(x):

f(x)=g(x)

Therefore, we need to solve for the previous equation for x:

Replacing the values of f(x) and g(x):

-3x+4=2

Subtract 4 from both sides:

-3x+4-4=2-4\\\\-3x=-2

Multiply both sides by -1

-3x(-1)=-2(-1)\\\\3x=2

Divide both sides by 3:

\frac{3x}{3} =\frac{2}{3} \\\\x=\frac{2}{3}

Therefore the value of x for which f(x)=g(x) is x=\frac{2}{3}.

Verify the result:

-3(\frac{2}{3} )+4=2\\\\-2+4=2\\\\2=2

A force is applied to the rim of a disk that can rotate like a merry-go-round, so as to change its angular velocity. Its initial
yawa3891 [41]

Answer:

A = B = C > D

Explanation:

Work done to stop the disc is given as

W = \Delta K

W = \frac{1}{2}I(\omega_f^2 - \omega_i^2)

so we have

(a) –2 rad/s, 5 rad/s;

(b) 2 rad/s, 5 rad/s;

(c) –2 rad/s, –5 rad/s; and

(d) 2 rad/s, –5 rad/s.

So we have

W_a = W_b = W_c = \frac{1}{2}I(5^2 - 2^2)

W_d = \frac{1}{2}I(2^2 - 5^2)

so we have

A = B = C > D
