Answer:
the electric field is 42.8×10^6 N/C
Explanation:
let k be the coulomb constant, Q be the charge distribution , R be the radius of the disk and x be the distance from the center.
k = 8.98755×10^9 N×m^2/c^2
Q = 6.1×10^-6 C
R = 4.9×10^-2 m
x = 3.1×10^-3 m
Answer:
speed in km/min:
0.3km/min
speed in km/h:
18km/h
speed in m/s:
5m/s
Explanation:
the average speed is defined as:

where
is the speed,
is the distance traveled, and
is the time
according to the statement:

and
(10 minutes are equal to a sixth of an hour which is 600 seconds)
Because the units in which the speed is required are not indicated, here are some options for the answer:
Depending on the units in which you need the speed, are the quantities you should use.
Speed in km / h (kilometers per hour):

speed in m / s (meters per second):

or the speed in km/min (kilometers per minute)

Answer:
B. Tomatos reflect red light
Explanation:
The only reason colors exist is because the objects with color reflect all other light except for what they are portrayed as. White reflects all colors, and black absorbs all colors.
