Answer:
Distance traveled in 1 liter = 40 km
Explanation:
Distance traveled = Energy / Opposing force = 40 x 10^6 J / 1000 N = 40000 m or 40 km
So, the car will moves to a distance of 40 km per liter under the opposing force of 1000 N…
Answer:
White light viewed through a prism is an example of a visible spectrum.
20km every 1 hr is what 20km/hr means.
so 3hrs is 20km*3=60km.
Given:
m(mass of the box)=10 Kg
t(time of impact)=4 sec
u(initial velocity)=0.(as the body is initially at rest).
v(final velocity)=25m/s
Now we know that
v=u+at
Where v is the final velocity
u is the initial velocity
a is the acceleration acting on the body
t is the time of impact
Substituting these values we get
25=0+a x 4
4a=25
a=6.25m/s^2
Now we also know that
F=mxa
F=10 x6.25
F=62.5N
