Acceleration formulae is:
a=Fnet/mass
According to the question
a=7500N/1500kg
a=5m/s sq.
Answer:
The new speed is 56.25 miles/hour.
Explanation:
Since speed = distance/time;
time = distance/speed.
While driving at 50 miles/hour, time taken for one to complete 1 mile is (1/50) hour
(1/50) hour = (1/50) × 3600s = 72 seconds.
So, if this time to complete 1 mile (72 seconds) is reduced by 8 seconds,
New time to complete 1 mile will be = 72 - 8 = 64 seconds = (64/3600) hour = 0.0178 hour
New speed would be = (1 mile/64 seconds) = (1 mile/0.0178 hour) = 56.25 miles/hour.
Hope this Helps!!!
Answer:
the force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface
Explanation:
Answer:
Green part of the visible spectrum.
X ray part of the electromagnetic spectrum.
Infrared part of the electromagnetic spectrum.
Explanation:
Wien's displacement law
Where, b = Wien's displacement constant = 2.898×10⁻³ mK
T = Temperature in kelvin
So, the wavelength would be of around the green part of the visible spectrum.
So, the wavelength would be of around the X ray part of the electromagnetic spectrum.
Human body temperature = 37°C = 37+273.15 = 310.15 K
So, the wavelength would be of around the Infrared part of the electromagnetic spectrum.
