Answer:

Electromagnetic waves are created by a charged particle that generates an electric field. The electric field creates a magnetic field. As the charged particle moves, the electric field and magnetic field keep changing, which causes the wave to move.

Consider a disk of radius 4.9 cm, having a uniformly distributed charge of +6.1 μC. The value of the Coulomb constant is 8.98755
gayaneshka [121]

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

You biked to the store in 10 minutes. The store was 3 km away. What was your average speed?
sineoko [7]

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:

s=\frac{d}{t}

where s is the speed, d is the distance traveled, and t is the time

according to the statement:

d=3km = 3,000m

and

t=10min=\frac{1}{6}h=600s (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):

s=\frac{3km}{\frac{1}{6}h }\\ \\s=18km/h

speed in m / s (meters per second):

s=\frac{3,000m}{600s}\\ s=5m/s

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

s=\frac{3km}{10min}\\ s=0.3km/min

Why do our eyes see the color red when we look at a tomato?
forsale [732]

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.

Find the velociity of a car which travels 35 m to the right over a period of 40 seconds
GalinKa [24]

Answer:

the velocity of the car is 0.875 m/s

Explanation:

v = d \div t \\ v = 35m \div 40sec = 0.875 \: m \: per \: sec

therefore the V of car is 0.875 m
