Answer:
D) They most likely died from not wearing a seatbelt.
Explanation:
Their death was caused by a "motor vehicle" (that's what MV stands for in this case). The most logical answer would be D.
Answer:
A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. ... It uses only two connections, even when 3 terminals (as in a potentiometer) are present.
Explanation:
Use Pascal's Law.
F1/A1 = F2/A2
F1 = 4400N
A1 = 0.020m^2
F2 = X
A2 = 0.040m^2
4400/0.020 = X/0.040
Cross multiply:
(4400 * 0.040) = 0.020X
176 = 0.020x
Divide both sides by 0.020
X = 176 / 0.020
X = 8800
The force is 8800 N
Answer:
Light travels very fast
Explanation:
Speed of light is normally estimated as 299704644.54 m/s in air hence radar systems have always been used to measure the distance travelled per unit time. By Galileo experimenting to get the speed of light in the above mentioned set-up, it would be difficult to estimate the speed of light. Therefore, it was obvious that Galileo could not estimate the speed of light. This is because the speed of light is very high. In vacuum, the speed of light is estimated as 299,792,458 m/s and this can't be accurately measured in such mentioned set up by Galileo.
