Only question 7. I keep getting it wrong and i’m not sure

Physics

Answer:

I think you just have to input the horizontal velocity component.

Explanation:

Assuming no air resistance

The horizontal velocity is constant at

vx = 17.5cos71 = 5.6974... = 5.70 i m/s

The vertical velocity varies with gravity

vy = 17.5sin71 + -9.81(22) = -199.273... = -199 j m/s

v = 5.70i - 199j m/s

arguably one should round to only two significant digits

A proton is going 2,000 m/s into a magnetic field of 300 T. How much force does it feel. The charge of a proton = 1.602 x 10^-19
NemiM [27]
This depends on the direction of the velocity vector to the magnetic field vector. The force is F=q(VxB)  ("x" is the cross product.)  The max force is when V and B are perpendicular.  Then F=qVB = (1.602e-19)(2000)(300) = 9.612e-14 N

When an atom that has no charge looses two electrons it becomes a
alex41 [277]

Answer: it becomes a positive ion

Explanation:

So, when an atom loses 2 electrons there will be no change in the number of neutrons. Therefore, an isotope will not form. Thus, it is concluded that when an atom with no charge loses two electrons, it becomes a positive ion.

If a cart of 10 kg mass has a force of 5 newtons exerted on it, what is its acceleration? m/s2
Elza [17]

Answer:

= 0.5 m/s²

Explanation:

  • According to Newton's second law of motion, the resultant force is directly proportion to the rate of change of linear momentum.

Therefore;<em> F = ma , where F is the Force, m is the mass and a is the acceleration.</em>

<em>Thus; a = F/m</em>

<em>but; F = 5 N, and m = 10 kg</em>

<em>  a = 5 /10</em>

    <u>= 0.5 m/s²</u>

Which is a more objective measurement, sound intensity or loudness, and why? 1. sound intensity is exactly same as loudness. 2.
fgiga [73]
The correct answer is:
<span>2. sound intensity is a more objective and physical attribute of a sound wave because loudness can vary from person to person

indeed, sound intensity is a measurable quantity, and so it is objective, while loudness is the subjective perception of the sound level, so it varies from person to person.</span>
