Answer: 15.66 °
Explanation: In order to solve this proble we have to consirer the Loretz force for charge partcles moving inside a magnetic field. Thsi force is given by:
F=q v×B = qvB sin α where α is teh angle between the velocity and magnetic field vectors.
From this expression and using the given values we obtain the following:
F/(q*v*B) = sin α
3.8 * 10^-13/(1.6*10^-19*8.9*10^6* 0.96)= 0.27
then α =15.66°
Answer:
1. it explains what's happening im the universe now
So that we do not contaminate it with microorganisms or garbage or other human stuff.
Gay-Lussac's Law shows the direct relationship between pressure and temperature for an ideal gas with constant volume. Mathematically it is
This particular has a lot of application in our everyday life. In cooking, for example, we apply this concept when using a pressure cooker. We increase/decrease the temperature to meet the right amount of pressure.
In addition, knowing that pressure increases when temperature does can help you with road safety. Knowing that temperature affects heat directly, we must be careful in making sure that tires are not overheated or else they explode out of too much pressure inside.
Answer:
b) the current and the voltage across the resistor
Explanation:
As soon as we close the switch then the current in the circuit will be zero because the inductor connected in series will not allow to change the current through it due to its inertial property
Since initial current through the inductor is zero so after connecting the key the current will still remains zero and then it will start increasing
The equation for current is given as

so as soon as the key is closed the current in the circuit is zero and hence the voltage across the resistor is also zero as we know

so correct answer will be
b) the current and the voltage across the resistor
