Displacement = (straight-line distance between the start point and end point) .
Since the road east is perpendicular to the road north,
the car drove two legs of a right triangle, and the magnitude
of its final displacement is the hypotenuse of the triangle.
Length of the hypotenuse = √ (215² + 45²)
= √ (46,225 + 2,025)
= √ 48,250
= 219.7 miles .
Velocity=3.4m/sec
Mass=30kg
so kinetic energy=1/2mv^2
=1/2×30×3.4×3.4
=15×3.4×3.4
=15×11.56
=173.4 kg m per second square
Answer:
A. The forces are the same size and in opposite directions.
Explanation:
Just as an opposite number will cancel a number: -1 +1 = 0, so an opposite force will cancel a force, with the result that the net is zero.
Answer:
hypothesis: Billy and Bob want to know if the amount of baking soda added to vinegar will affect the height a rocket will launch. They will measure the height of the rocket launch in meters
Explanation:
Answer:
I=0.05 Amper
v=9 volts
Explanation:
I=V/R1
l=6/120=0.05Amper
voltage of 180ohm =IR2=0.05×180=9volts
