Answer:
uh i think 1.2km im probably so wrong
Explanation:
There are so many answers. It depends on which field of physics you are working on.
You could calculate velocity from momentum or kinetic energy knowing also the object's mass for example.
Answer: B
R = 2 ohms
Explanation:
When resistors are connected in parallel, the equivalent resistance R will be less than the least resistance.
1/R = 1/R1 + 1/R2 + 1/R3 + 1/R4 + 1/R5
Since the 5 resistors are 10 ohms each, substitute them in to the formula
1/R = 1/10 + 1/10 +1/10 + 1/10 + 1/10
The LCM = 10
1/R = 5/10
Reciprocate both sides
R = 10/5 = 2 ohms
The correct option is B
Answer: 33.3 m/s^2
Explanation:
Here we need to use the second Newton's law.
F = m*a
Force equals mass times the acceleration.
Here we know that the force is F = 4000 N, and the mass is 120kg, then the acceleration must be:
4000 N = 120kg* a
a = (4000/120) m/s^2 = 33.3 m/s^2
Stopping on snow and ice may require up to ten times
the distance than normal conditions.
In normal conditions you can drive easily, but when
there is snow, ice, fog, rain, it is difficult to drive. Some people thought a
stopping distance was twice as in normal condition but it can increase up to
ten times in snow and ice.
