Answer:
B = 0.15 T
Explanation:
To find the magnitude of the magnetic field you use the following formula:
( 1 )
m: mass of the electron = 9.1*10^-31 kg
v: velocity of the electron = 3*10^6 m/s
q: charge = 1.6*10^-19
r: radius = 0.11mm = 0.11*10^-3 m
You replace the values of the parameters in the equation (1).

the magnetic field has a magnitude of 0.15 T
For A: LED outdoor lighting.
Because you want it to be able to withstand outdoor conditions. If it can’t withstand... there’s no light... no light... no advertisement.
For B: it would be lithonium lights. It’s found in most offices and gives the best light for working day or night.
For C: you’ll want elevated lights so they are noticed for the plane to land and for people and others to see.
For D: you want white light and you want it to also be able to withstand outdoor conditions. Cars and people need to see at night, especially at night. Solar would be a great choice.
Hope this helps! I tried hard.
Answer:

standard decimal form of 6.36*10^4 is
6,3600.0
Heat energy is a form of kinetic energy
If a gun is sighted to hit targets that are at the same height as the gun and 85 m away at the same height, how low, as a positive number in meters, will the bullet hit if aimed directly at a target 180 m away
The muzzle velocity of the bullet is 275 m/s
Answer:
y = -1.1109 m
Explanation:
Range = 
range = 85 m
velocity = 275 m/s
g = 9.8 m/s²







If the bullet is aimed at a target 180 m, time required to travel 180 m with horizontal component will be;

t = 0.6546 sec
To determine, how low as a positive number in meters.

y =

y = 0.9909 - 2.1018
y = -1.1109 m
