Answer:
1. Direction of B is parallel to V
2. Magnetic field is most uniform between the flat, parallel magnetic poles of a c-shaped magnet
3. Doubling B would double the magnitude of the force on the proton
4. Magnetic field is strongest near the north and south poles
5. The initial direction of the proton is toward the right of the screen. The field deflects the proton toward the top of the screen
6. Assume that you are viewing the diagram on a flat computer screen. Perpendicular to the screen, pointing toward you.
7. A stationary point charge doesn’t generate a magnetic field in the space around it.
8. Proton enters magnetic field at a speed of 7.8 x 10^4, charge of proton equal to 1.6 x 10^-19 is 2.6 x 10^-14 N
9. A few times every million years
10. Magnitude |q|vB directed towards bottom of screen
Explanation:
Answer:
101.32 rounded to 1 significant figure is 100. 20.1234 rounded to one significant figure is 20, and 212.1 rounded to one significant figure is 200.
100 + 20 is 120, and 120 - 200 is -80.
Explanation:
The halogens group, this is also the group that is highly reactive. The halogens form salts with group one.
Answer:
A) Spherically symmetric about a point in the constellation Sagittarius and concentrated in that direction
Explanation:
The globular clusters are present mainly in the direction of Sagittarius with the center of the system of globular cluster being measured as a spherical cluster cloud such that the center of the Milky Way can be taken as being in the Sagittarius constellation
Explanation:
pure definition :
kilo means 1000 (thousand).
so, a km or kilometer is 1000 m or meter.
2000 km = 2000 × 1000 m = 2,000,000 meters
