to get it u have to multiple 6=00 time 89 to get the number 21 than plus it by 22 what is 31
Given Information:
Mass = m = 20000 kg
Height of ramp = h = 0.840 m
Length of ramp = L = 20 m
Required Information:
Uphill Force = F = ?
Answer:
F = 8232 N
Explanation:
The force can be found using the equation
F = mgsinθ
Where m is the mass of block, g is the acceleration due to gravity
Since the ramp can be modeled as an inclined plane so it can formed into a triangle, recall that in right angle triangle sinθ is equal to opposite over hypotenuse. The opposite is the height and hypotenuse is the ramp surface.
sinθ = h/L = 0.840/20 = 0.042
F = 20000*9.8*0.042
F = 8232 N
Therefore, an uphill force of 8232 N would be needed.
To calculate the velocity relative to car A, you have to add the opposite of the velocity of car A to car B.
the velocity of car B relative to car A:
(let east and north directions be positive)
v = v (car B) - v(car A)
v(east-west direction) = -120 * cos 30° - 110
v(north - south direction) = -120 * sin 30° - 0
Answer: electrolyte solutions
Explanation:
Both the conservation of energy and the conservation of matter is important because, without each other, the natural equilibrium will be disrupted.
<h3>What is the law of conservation of energy?</h3>
According to the Law of conservation of energy. Energy can not be created nor be destroyed it can transfer from one to another form.
The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.
The conservation of both is important because without each other, the natural equilibrium will be disrupted, and it aids in the maintenance of the food chain.
It is seen as such because there would be no energy without matter and vice versa.
Hence both the conservation of energy and the conservation of matter is important
