Answer:

Explanation:
Given that,
Mass of the car, 
Initial speed of the car, 
Final speed of the car, 
To find,
The maximum mass of grain that it can accept.
Solution,
We know that according to the law of conservation of momentum, the initial momentum is equal to the final momentum.




Therefore, the maximum mass of grain that it can accept is 2554.83 kg. Hence, this is the required solution.
Answer:
447 K
Explanation:
25 C = 25 + 273 = 298 K
Assuming ideal gas, we can apply the ideal gas law


Since pressure is tripled, then
. Volume is halved, then 

Vertical forces:
There is a force of 579N acting upward, and a force of 579N
acting downward.
The vertical forces are balanced ... they add up to zero ...
so there's no vertical acceleration.
Not up, not down.
Horizontal forces:
There is a force of 487N acting to the left, and a force of 632N
acting to the right.
The net horizontal force is
(487-left + 632-right) - (632-right - 487-right) = 145N to the right.
The net force on the car is all to the right.
The car accelerates to the right.
One should check the battery every week.
A battery if not maintained properly can cause it to die earlier or get damaged. The reasons why should the battery be checked regularly is that due to improper management of the battery and also the weather conditions, the battery usually gets corroded easily and the battery won't be able to work properly.
The connections must be checked properly so that the battery gets charged properly and should not die while driving.
<span>wavelength of an electron l = h/p = 8.7 x 10^-11
h --> Planck's Constant
m --> Momentum
Wavelength l = h/p = h/mv = > v = h/(m*l)
From the given values,
m = 9.1 x 10^-31 kg
l = 8.7 x 10^-11 m
h = 6.626x10^-34 Js
v = 6.626x10^-34/ ((9.1 x 10^-31)*(8.7 x 10^-11))
The velocity of electron v = 8.37x10^6 m/s</span>
