The speed of car is 106.67 miles per hour
To solve problems involving speed and distance we are required to first find speed or distance travelled in an hourly timeframe
It is given that car takes 4 hours to cover the distance at a speed of 40 miles per hour
Therefore, total distance travelled by the car= speed x time
= 40 miles per hour x 4 hour
=160 miles
We are required to find the speed of the car if the distance is to be covered in 1.5 hours
We are required to find the speed by the formula speed= Distance/time
distance= 160 miles time = 1.5 hour
speed= 160/1.5=106.666=106.67 miles per hour
Hence the speed is 106.67 miles per hour

Answer:
Considering Tarzan as a point mass at point L and using the equation for a simple pendulum:
P = 2 pi (L / g)1/2
P^2 = 4 pi^2 L / g
L = g P^2 / (4 pi^2) = 9.8 m/s^2 * 7.27^2 s^2 / (4 pi^2) = 13.1 m
Answer:
1989.6Kg
Explanation:
The computation of the mass of the other body is given below:
As we know that
F = G × m1 × m2 ÷ r²
Here the G would have the constant value i.e. 6.67 × 10^-11Nm² / kg².
Now
6.5 × 10^-7N = 6.67 × 10^-11Nm² / kg² × 60Kg × m2 / (3.5m) ²
m2 = (F × r²) / (G × m1)
m2 = (6.5 × 10^-7N × (3.5m) ²) ÷ (6.67 × 10^-11Nm² / kg² × 60Kg)
= 1989.6Kg
Answer:
The answer here would be light bulb.
Explanation:
An Illuminated object is simply something that reflects light. And everything in the list is illuminated except the light bulb. Humans reflect light in the same way as desks and sidewalks. If we didn't we wouldn't technically be able to see other humans unless they were luminous. This brings me to the nest point. A light bulb is a luminous object because <em>it creates light on its own. </em>
A good example would be this:
The Sun is a luminous object
The Moon is a illuminated object
I hope this helped and didn't confuse you more, I kind of went all over the place with the explanation. Either way, if you need more help feel free to let me know! :)
