Answer:
the acceleration 
Explanation:
Given that:
the initial speed v₁ = 0 m/s i.e starting from rest ; since the car accelerates at a distance Δx = 6 miles in order to teach that final speed v₂ of 63.15 km/h.
So; the acceleration for the first 6 miles can be calculated by using the formula:
v₂² = v₁² + 2a (Δx)
Making acceleration a the subject of the formula in the above expression ; we have:
v₂² - v₁² = 2a (Δx)




Thus;
Assume the car moves in the +x direction;
the acceleration 
Answer:
Explanation:
An acid has H as the metal as in HCl
A base has OH as the nonmetal. (so Ca(OH)^2 is a base)
A salt has neither.
Answer:
Incomplete question but the closest ans is
A) The displacement is not zero
Explanation:
For work to be done, the direction of force has to be parallel to or in the same direction as the displacement, this can then be calculated by
θ
Where θ is the angle between direction of force and direction of displacement
By this equation,
if Force is zero, W is zero
if displacement is zero, W is zero
if force and displacement are perpendicular θ=90, cosθ = 0
So A is the cloest choices
The first collision because a greater amount of momentum must be taken and used in order to push the cart back, giving it a greater mass and impulse
The correct statement should be: Descriptive investigations involve collecting data about a system, but not making comparisons.
so i believe the statement above is false
In descriptive investigations, we shall not make any hypothesis for the situation and we just need to fully record all obeservations.
By doing this, we could fully analyze the variables without comparing and manipulating it.
