Answer:
length
Explanation:
SI unit of volume = m^3
SI unit of area = m^2
volume unit / Area unit = m^3 / m^2
i.e, unit of length
Answer:
2.5 ms⁻²
Explanation:
By Newton's 2nd law,
The rate of change of momentum is directly proportional to the unbalance force applied on the object,
By that you can get the equation,
F = ma ⇒ a = F/m
where terms are in usual meaning
a = 3750/1500 = 2.5 ms⁻²
The printing press had dramatic effects on European civilization. Its immediate effect was that it spread information quickly and accurately. This helped create a wider literate reading public.
Answer:
137.34 J
Explanation:
Info given:
mass1 = 2kg
height1 = 3m
mass2 = 4kg
height2 = 5m
g = 9.81m/s^2
PE = mgh
plug in info we have:
for first mass:
mgh = (2kg)(9.81m/s^2)(3m) = 58.86 J
for second mass:
mgh = (4kg)(9.81m/s^2)(5m) = 196.2 J
Difference: 196.2 J - 58.86 J = 137.34 J
Answer:
The tension is 384 N.
Explanation:
To calculate the acceleration, we know the velocity and the time, so:
a=Δv/t
To calculate the tension we need to apply Newton's second law:
∑F=m*a
