As a moon follows its orbit around a planet, the maximum grav- itational force exerted on the moon by the planet exceeds the min

Answer:

The outcome of adding 999mm to 100m is 101m.

Explanation:

That's my belief.

(6-16)/4.0=-2.5 m/s²
The car's acceleration is -2.5 m/s²

Answer:

force = 6.53× N

Explanation:

Provided data

downward force = 0.60 m

mass m = kg

distance h = 0.40 m

to determine

magnitude of the downward force

solution

we know here mg is apply 0.4 m away from support and

thus applied force is d = 0.6 m from support

therefore

by balancing torque we can compute force

as

force = mass × g × h / d

substituting the values

force = mass × g × h / d

force = ( × 9.81 × 0.4 ) / 0.6

force = 6.53× N

The star is moving away from our planet. To elaborate on the Doppler shift: This phenomenon, related to the Doppler effect, is the variation in the perceived frequency or wavelength (color) of a wave when the source of the waves and the observer are in motion relative to one another. Consequently, it can be inferred that as an object recedes, it exhibits more redshift in its spectrum. For instance, when a star moves away, its spectral lines shift towards the red end of the spectrum, whereas if it approaches Earth, the spectral lines move towards blue. Given that the peak wavelength is roughly 650 nm—which is associated with red—it can be concluded that the star is indeed moving away from Earth.

Answer:

The total energy saving achieved will be 0.8 KWH

Explanation:

It is provided that there are 50 long light bulbs rated at 100 W, thus the total power consumed by 50 bulbs equals 100×50 = 5000 W = 5 KW

Additionally, 30 bulbs are rated at 60 W

Consequently, the total power consumption of 30 bulbs is 30×60 = 1800 W = 1.8 KW

The cumulative power of all 80 bulbs is 1.8 + 5 = 6.8 KW

Considering the operation time of 3 hours

We know that energy

Now, the power consumption per CFL bulb equals 25 W

Thus for 80 bulbs, power equals 80×25 = 2000 W = 2 KW

So the energy for 80 bulbs amounts to 2×3 = 6 KWH

Hence, the overall energy saving is 6.8 - 6 = 0.8 KWH
