Breaking down food molecules
Answer:
Explanation:
Given
Car starts from the state of rest and acquires a velocity of in 6 minutes
Final velocity in m/s is
Using equation of motion
Distance covered in 360 s
Answer:
B is correct. Electrons are added to the rod.
Explanation:
Because the fur lose electrons to the rode and because positively charged while the rod because negative
Answer:
v_{4}= 80.92[m/s] (Heading south)
Explanation:
In order to calculate this problem, we must use the linear moment conservation principle, which tells us that the linear moment is conserved before and after the collision. In this way, we can propose an equation for the solution of the unknown.
ΣPbefore = ΣPafter
where:
P = linear momentum [kg*m/s]
Let's take the southward movement as negative and the northward movement as positive.
where:
m₁ = mass of car 1 = 14650 [kg]
v₁ = velocity of car 1 = 18 [m/s]
m₂ = mass of car 2 = 3825 [kg]
v₂ = velocity of car 2 = 11 [m/s]
v₃ = velocity of car 1 after the collison = 6 [m/s]
v₄ = velocity of car 2 after the collision [m/s]
Answer:
g= 1.8 m/s²
Explanation:
From conservation of energy we know:
Solving for g with h being the height of the ramp with angle ∅ and length L:
(1)
The velocity v at the bottom of the ramp for a constant acceleration a in a time t is given by:
(2)
Plugging equation 2 in to equation 1:
(3)
