ANSWER: 170 Feet
REASON: with good breaks and a dry road your car should stop and skip 170 feet, with perception and reaction time of stopping you should stop within 170 feet
Gravitational potential energy stored in cat= mgh ( m= mass of cat, h = height of cat from ground) = 7x9.8x3 = 205.8 J
Answer:110v
Explanation:
Current=100 amperes
Resistance=1.1 ohms
voltage=current x resistance
Voltage=100 x 1.1
Voltage=110v
Answer:
A pair of light or sound waves will experience interference when they pass through each other. Destructive interference occurs when the maximal of 2 waves are 180 degrees out of phrase: A positive displacement of one wave is canceled exactly by a negative displacement of the other wave.
Answer:
f = 347.08 N
Explanation:
The frictional force exerted by the floor on the refrigerator is given as follows:
where,
f = frictional force = ?
μ = coefficient of static friction = 0.58
W = Weight of refrigerator = mg
m = mass of refrigerator = 61 kg
g = acceleration due to gravity = 9.81 m/s²
Therefore,
<u>f = 347.08 N</u>
