According to the second law of Newton, the acceleration is directly proportional to the net force acting on the object:
[tex]F=m\cdot a[/tex]From this formula, we can also see that the acceleration is inversely proportional to the mass: For the same force, if the mass increases, the acceleration decreases.
Therefore the correct option is d.

A singly charged positive ion has a mass of 3.3x10-26 kg. after being accelerated from rest through a potential difference of 933 v, the ion enters a magnetic field of 1.43 t along a direction perpendicular to the field. The radius of the circular path of the ion in the field is (r)= 1.982 cm.
What is energy?Energy is a term that means the object is affected by some amount of force and move a distance. That is called the energy. It can be measured in Joule.
How can we calculate the radius of the path?To calculate the radius we are using the formula here,
r= mu/Bq
Where we are given,
m = The mass of single positive charged ion.= 3.3×10⁻²⁶kg.
q= The charge of the single positive charged ion.= 1.602×10⁻¹⁹ C
B = The magnetic field for the electric field. = 0.92 T
But we don't know the term, u= the velocity of the single positive charged ion.
So we have to calculate the velocity of the single positive charged ion. To calculate the velocity we are using the formula,
(1/2)mu²=qv
Here we are given,
v= The potential difference of the electric field. = 933v.
We have to calculate the velocity=u, as Conservation of energy we know,
(1/2)mu²=qv
Or,(1/2)mu²=ev
Or, u²= (2×1.602×10⁻¹⁹×933)/(3.3×10⁻²⁶)
Or, u=91325.9 m/s.
So from this we know the velocity of the ion, u=91325.9 m/s.
Now, we have to calculate the radius in a magnetic field= r,
r= mu/Bq =mu/Be
Or, r= 3.3×10⁻²⁶×91325.9/0.92×1.602×10⁻¹⁹
Or, r=0.01982m
Or, r=1.982 cm.
So from the calculation we can surely say that, The radius of the circular path of the ion in the field is (r)= 1.982 cm.

an athlete lifts a 350 n set of weights from ground level to a position over her head, a vertical distance of 1.90 m. how much work (in j) does the athlete do? assume the weights are moved at constant speed.
Answers
Work is measured in joules or newton-meters
It may be thought of as force * distance
If there were acceleration in this problem, the force would be more than the weight, but because the speed is constant force = weight.
given,
force= 350N
Distance= 2m
work= ?
Work = Force * Distance
= 2m * 350 N
= 700 j or 700 N*M
If you're looking at this from an energy standpoint, you can just consider the final PE as the energy required because there is no KE at the end. so,
PE = m*g*h
and m*g = 350N
h= 2m
PE = 700j or 700 N*M
Hence, the 700N*M work is done by athlete.

According to the Law of Conservation of Linear Momentum, the total linear momentum of the system before and after the collision remains the same. Then:

Answers
The initial resistance of one resistor r in ohms in series combination is 28.5 Ω.
The resistance depends on the used combination. The resistor combination can be combined in 2 ways which are series combination and parallel. In series combination, the resistance will be added up for each resistor. It can be written as

When there is relative motion between the fluid layers or between the fluid and solid surface, the fluid's internal property known as viscosity is created. This relative motion is being resisted by viscosity.
Derivations of the equations of motion—the connections for the conservation of mass and momentum—in rectangular,
coordinates that are spherical and cylindrical. The entire body of experimental data suggests that the fundamental equations of fluid mechanics are in fact those listed below, and that they apply to any circumstance where a Newtonian fluid is flowing, in theory.
Viscosity, a characteristic of fluids, is produced when there is relative motion between the fluid layers or between the fluid and solid surface. Viscosity prevents this relative motion from happening.
Unfortunately, due to their all-encompassing nature, their analytical solution is challenging or impossible unless the circumstances are quite straightforward.
However,
These "Navier-Stokes equations" must be understood for the following reasons.
reasons:
1. They result in the analytical and precise resolution of some basic yet significant problems.
issues.
2. They serve as the foundation for additional chemical engineering research in various fields.
3. A few reasonable simplification assumptions can frequently result in
for many engineering problems, approximation solutions are eminently acceptable purposes. Typical examples can be found in the study of boundary layers, the use of films to cover substrates, waves, lubrication, and inviscid (irrotational) flow.

if you are on top of mount Everest and do a small hop without moving forward, would you still be pulled down by gravity? explain it and also answer my other newest question.
Answers
Explanation:
Gravity would still pull you down although it wouldn't affect you as much because there is less gravitational pull in high places such as Mt. Everest.
