Answer: the direction of the magnetic force on the electron will be moving out of the screen, perpendicular to the magnetic field.
Explanation:
The magnetic force F on a moving electron at right angle to a magnetic field is given by the formula:
F = BqVSinØ
If an electron moves in the plane of this screen toward the top of the screen. A magnetic field is also in the plane of the screen and directed toward the right. Then, the direction of the magnetic force on the electron will be perpendicular to the magnetic field
According to the Fleming's left - hand rule, the direction of the magnetic force on the electron will be moving out of the plane of the screen.
Answer:
The correct answer is no.
Explanation:
The temperature of a person changes depending on their age, the physical activity they are doing and until the time of day.
There is an established average temperature that is 98.6 ° F (37 ° C) as a healthy temperature.
If the temperature exceeds 100.4 ° F (38 ° C) it means that you may be ill or have an infection.
The difference in temperature by age is very minimal, but it is still a difference. Let's see:
- Babies and children: from 97.9 ° F (36.6 ° C) to 99 ° F (37.2 ° C).
- Adults: from 97 ° F (36.1 ° C) to 99 ° F (37.2 ° C).
- Adults over age 65: 98.6 ° F (36.2 ° C).
Answer:
Makes it hard to go to sleep at night
Explanation:
Answer:
a) 
, b) 
Explanation:
a) According to the First Law of Thermodinamics, the system is not reporting any work, mass or heat interactions. Besides, let consider that such box is rigid and, therefore, heat contained inside is the consequence of internal energy.
The internal energy for a monoatomic ideal gas is:
Let assume that cubical box contains just one kilomole of monoatomic gas. Then, the temperature is determined from the Equation of State for Ideal Gases:
The thermal energy contained by the gas is:
b) The physical model for the cat is constructed from Work-Energy Theorem:
The speed of the cat is obtained by isolating the respective variable and the replacement of every known variable by numerical values:
Its 21!! sorry i was late! :)
