I think they're called beta rays/particles
The answer to your question is a nonelectrolyte.
We study the movement of each body separately. For the mass body A: vector: T + Na + Ga + Ff = ma * a.Scalar: on the axis Ox: ma * g * sinα-T-Ff = ma * a
On the axis Oy: Na-ma * gcosα = 0=>Na=ma * g*cosα
Ff=μ*N=μ*ma * g*cosα
ma * g * sinα-T-μ*ma * g*cosα=ma*a
For mass body B: vector: Gb + T = mb * a.Scalar: by projection of the vector relation on the axis Ox:T-mb*g=mb*a
<h3><u>Answer;</u></h3>
C. 228 Joules
<h3><u>Explanation;</u></h3>
<em><u>Efficiency of a machine is the energy or work output, divided by the energy or work input, and expressed as a percentage. </u></em> An ideal machine would have an efficiency of 100%.
Efficiency = (work output/work input) × 100%
work input = 350 joules, efficiency = 65.1%
Work output = 350 j × 65.1/100
= 227.85
<u>≈ 228 Joules</u>
Answer:
D. No, because the student needs to know the direction that the force is applied
Explanation:
The change in momentum depends on the direction of the force as well as its magnitude. Since the graph only supplies force magnitude information, it is insufficient to allow the student to calculate the change in momentum.
