Answer:
2 1/2 m/s^2 or 2.5m/s^2
Explanation:
From the question
final velocity v =25m/s
Initial velocity u =10m/s
time = 6 seconds
acceleration a = ?
Using the equation for linear motion
v = u + at
25 = 10 + a x 6
25 = 10 + a6
Subtract 10 from both sides
25-10 = 10 + a6 -10
25 - 10 = 10 -10 + a6
15 = a6
Divide both sides by 6
15/6 = a6/6
5/2 = a
a = 2 1/2 m/s^2 or 2.5m/s^2
Answer: question D is trough
Explanation: I learned this already
Answer:
answer is 18.6111
you can easily convert km/hr into m/s
just divide it by 3.6
Average intensity of electromagnetic wave is given by
I= (speed of light*permittivity*sq. electric field)/2
Speed of light = 3x10^8 m/s
Permittivity = 8.85x10^-12
Therefore,
Electric field = sqrt (2I/ (speed of light xpermittivity)) = sqrt ((2*4.50)/(3*10^8*8.85*10^-12)) = 58.22 V/m
