The increase in temperature that will result if 225.0 g of copper absorbs 5000 J of heat energy is 57.72°C.

<h3>How to calculate temperature change?</h3>

The temperature change of a substance can be calculated using the following formula:

Q = m × c × ∆T

Where;

  • Q = quantity of heat absorbed or released
  • m = mass of substance
  • c = specific heat capacity
  • ∆T = change in temperature

5000 = 225 × 0.385 × ∆T

5000 = 86.63∆T

∆T = 5000/86.63

∆T = 57.72°C

Therefore, the increase in temperature that will result if 225.0 g of copper absorbs 5000 J of heat energy is 57.72°C.

Xavier is administering medication to his patient. He administers four cups 4 points
Galina-37 [17]

Answer:

11 ounces

Explanation:

The patient gets 11 ounces of liquid.

From the description of this problem:

        Xavier administers  four cups of liquid each containing two ounces

The number of ounces in the four cups = 2 x 4  = 8ounces

Also,

   One cup of the liquid contains 3 ounces.

Total number of ounces administered  = 8 + 3  = 11 ounces.

Valentin [98]

Answer:

ωf = 4.53 rad/s

Explanation:

By conservation of the angular momentum:

Ib*ωb = (Ib + Ic)*ωf

Where

Ib is the inertia of the ball

ωb is the initial angular velocity of the ball

Ic is the inertia of the catcher

ωf is the final angular velocity of the system

We need to calculate first Ib, Ic, ωb:

Ib = mb*(L/2)^2=0.15*(1.2/2)^2=0.054 kg.m^2

Ic = mc/12*L^2=2.2/12*1.2^2=0.264 kg.m^2

ωb = Vb / (L/2) = 16 / (1.2/2) = 26.67 m/s

Now, ωf will be:

\omega f = \frac{Ib*\omega b}{Ib + Ic}  = 4.53rad/s

There are 120 degrees in a straight angle. true false
mixas84 [53]
That would be false.
Straight angle= 180 degrees
Obtuse angle= Above 90, and lower than 180
Acute angle= Below 90
Hope this helps! (:
