The distance starting from the point to the lighthouse would be regarded as the hypotenuse.
And also will be the radius of the circle the beam of light is generating at that point.
So get the radius first
r = sqrt (1^2 + 5^2)
r = 5.099 km
find the circumference:
C = 2*pi * 5.099 km
C = 2 * 16.01898094
C = 32.04 km
Then find the speed in km/sec
One revolution: 60/2 = 30 sec per revolution
Speed = 32.04 km/30 sec
S = 1.068 km/sec is the speed of light
Use P=F/a
whereas P= 350000 and a=.9m2
substitute into the formula we get
350000=f/.9m2 multiply .9 on both sides as LHS=RHS WE get 315000 Newtons as the answer
The correct answer is A. Solid
Gas has the least density because the atoms and molecules spread to fit the container. Liquids is between solid and gas when it comes to density, while solid has the highest density due to the way the molecules are tightly and closely connected.
Answer:
350 W
Explanation:
50 steps × 0.12 m/step = 6 m
Power = work / time
P = mgh / t
P = (60 kg) (9.8 m/s²) (6 m) / 10 s
P = 352.8 W
Rounding to two significant figures, the power is 350 W.
Answer:
B
Explanation:
A normal heart rate is from 85-95% the other heart rate is not normal because your heart is beating more than normal
