Answer:33.33 m/s
Explanation: In order to calculate this conversion we have to use:
1 mile = 1.6 km and also to convert Km/h to m/s the factor is 1000/3600
then we have: 75*1.6*0.27=33.33 m/s
You must find the component of the force before calculating
Answer:
length of selfie-stick is 1.62 m
Explanation:
Given data
image size h1 = 5 mm = 5 ×
m
focal length = 4 mm = 4 × m
distance h2 = 2.032 m
to find out
How long of a selfie-stick
solution
here we find first magnification
that is M = h1 /h2
M = 5 × / 2.032
M = 2.46 ×
and we know M = p/q
so p = Mq = 2.46 × q
so we apply lens formula
1/f = 1/p - 1/q
1/ 4 × = 1 / 2.46 × q - 1/q
q = 1.622 m
so length of selfie-stick is 1.62 m
The answer is false. I know for a fact it is but i dont remember which ones.
1.) Ohm's law is understood as I = V/R. Given that resistance is constant, then voltage changes directly proportional to current.
2.) The more current that passes through a lightbulb, the brighter it glows. The higher the current, the higher the power, where power determines the brightness of a bulb.
3.) A bulb has a specific limit to how much power (Watts) it can handle. Going over the limit would cause the bulb to burn out.
4.) When a bulb burns out, no current will be able to pass through the filament.
