Answer:
A
Explanation:
The closer an object is to light speed, the slower time flows for the object
Answer:
The skidding distance would be doubled
Explanation:
When the truck applies the brakes and slows down, its motion is a uniformly accelerated motion, so its skidding distance can be found by using the suvat equation
where
v = 0 is the final velocity (zero since the truck comes to a stop)
u is the initial velocity
a is the acceleration
s is the skidding distance
The acceleration can also be written as
where F is the force applied by the brakes and m the mass of the truck. Substituting into the previous equation,
We see that the skidding distance is proportional to the mass: therefore, if the mass of the truck is doubled, the skidding distance will double as well.
your answer is.....
D. have a large atomic radius
although they also increase going from left to right so if D is incorrect, B might be your answer. it depends on context of the lesson.
Answer:
velocity = 15m/s
Explanation:
momentum of the object = 480kg/ms
nass of object = 32 kg
velocity of object = ?
momentum = velocity × mass
velocity = momentum / velocity
= 480kg/ms/32kg
= 15m/s
