The bulb of the thermometer placed at the head of a distillation apparatus should be adjacent to the condenser. Explain the effe
Margarita [4]

Answer:

a) If the thermometer is placed well below the condenser it will record a higher temperature.

b) If the thermometer is placed well above the condenser it will record a lower temperature.

Explanation:

A) ) If the thermometer is placed below the opening to the condenser, a higher temperature will be recorded than if it is placed close to the opening since the bulb is contact with both the vapuor and liquid that is entering the condenser.

B) If the thermometer is placed above the condenser, a lower temperature will be recorded than if it is placed close to the opening since the bulb is not in full contact with both the vapuor and liquid that is entering the condenser.

A current-carrying wire oriented north-south and laid over a compass deflects the compass 8° to the east. What is the magnitude
zhenek [66]

2.8 \times 10^{-6}\ T is the magnitude of the magnetic field made by the current

<u>Explanation:</u>

Given data:

\theta=8^{\circ}

Magnetic field of earth, B_{\text {earth}}=2 \times 10^{-5}\ \text {tesla}

We need to find the magnetic field of wire, B_{\text {wire }}

The compass needle moves toward a direction of magnetic field. The current in wire makes a magnetic field in available space where the compass is on the ground. The vector sum of the Earth's magnetic field and the wire's magnetic field represents the net magnetic field, as shown in the attached drawing, expressing the angle:

                   \tan \theta=\frac{B_{\text {wire}}}{B_{\text {earth}}}

By substituting the given values, we get

                  B_{\text {wire}}=\tan \theta \times B_{\text {earth}}=\tan 8^{\circ} \times 2 \times 10^{-5}=0.1405 \times 2 \times 10^{-5}

                  B_{\text {wire}}=0.28 \times 10^{-5}=2.8 \times 10^{-6}\ T

What is the momentum of a volleyball with a velocity of 50 mph and a mass of .5 kg?
Romashka-Z-Leto [24]
The formula for momentum is p=mv (mass multiplied by velocity), so in this problem, p=50(.5)=25=p or in other words, momentum.
