Answer:
F=mass×acceleration
Acceleration=force÷mass
6.2/2=3.1
The resulting acceleration is 3.1 m/s2
Answer:
3.1 m/s²Explanation:
We know the relation :
Force = Mass x AccelerationWe can rearrange so it is equal to acceleration :
Acceleration = Force / MassHere :
Mass = 2.0 kgForce = 6.2 NSubstituting the values in our rearranged equation :
a = 6.2 / 2.0a = 3.1 m/s²Therefore, the resulting acceleration of the object will be 3.1 m/s²

Based on the tug of war pictured below, what is the net force? –190 n 10 n –10 n 190 n
The net force in the tug of war which is shown in the picture provided will be 0N.
What is a Force?This is defined as the power exerted on a body and the unit of Force is referred to as Newton.
In the tug of war, the net force is gotten by summing up all the forces.
–190N + 10N –10N + 190N = 0N.
Therefore the net force is 0N.

The bicycle lamp glows when the bicycle's generator touches the wheel. This is because
Answer:
The dynamo has a wheel that touches the back tyre. As the bicycle moves, the wheel turns a magnet inside a coil. This induces enough electricity to run the bicycle's lights. The faster the bicycle moves, the greater the induced voltage - and the brighter the lights.
Because of the bicycle's actions, the wheel turns a magnet internal a coil. This induces enough strength to run the bicycle's lighting fixtures. The faster the bicycle movements, the greater the caused voltage - and the brighter the lights.
What type of modern is produced with the aid of a bicycle dynamo?A trendy dynamo creates an instantaneous modern-day (DC) – a one-directional waft of electrical rate. A bicycle dynamo creates an alternating current (AC), which reverses course from time to time.
A dynamo is a tool normally positioned inside the hub of a motorcycle's wheel that converts the energy generated by means of the wheel spinning to electric power. That energy is then used to run front and rear dynamo lights at the bike, offering constantly-on illumination without the want to change the lighting.

If it is brittle, dissolves easily in water, has a high melting point, and conducts electric current it is a(n) __________.
Answer:
Ionic Compound
Explanation:
We know that an ionic compound dissolves easily in water. Its melting point is very high, and it is a conductor.
The equation for Ionic Compound (IC) versus Electricity (EC) is
IC=1/2 divided by EC
EC is the base for the mathematics, so EC is a base warmth at 360.
360 divided by 1/2 is 180
That is the speed in which the current has.

Part 1- An ideal gas, initially at a volume of 1.71429 L and pressure of 7 kPa, undergoes isothermal expansion until its volume is 6 L and its pressure is 2 kPa. Calculate the work done by the gas during this process. Answer in units of J.
Part 2- Find the heat added to the gas during this process.
Answer in units of J.
Part 1- The work done by the gas during this process will be 5.65 ×10⁻³ kJ.
Part 2-The heat added to the gas during this process will be 5.65 ×10×10⁻³ kJ.
What is work done by the gas?Work is the product of pressure p and volumes V during a volume change for such a gas. The work seems to be the area under the curve that indicates how the state changes.
The work done under the isothermal process is;
[tex]\rm W= P_1V_1 log_e(\frac{P_1}{P_2} )\\\\ W= 7 \times 1.71429 \times 10^{-3} log_e(\frac{7 }{2} )\\\\\ W= 0.0044 \ kJ[/tex]
For the isothermal process;
ΔU=0
[tex]\rm \triangle Q = \triangle E + \triangle W \\\\ Q = 0 + 5.65 \times 10^{-3}\\\\ Q = 5.65 \TIMES 10^{-3} \ kJ[/tex]
Hence, the work done, and the heat added by the gas during this process will be 5.65 ×10⁻³ kJ and 5.65 ×10×10⁻³ kJ respectively.

A hand exerciser utilizes a coiled spring. A force of 108.0 N is required to compress the string by 0.0191 m. Determine the force needed to compress the spring by 0.0440 m. N
By Hooke's law, the spring exerts a restoring force with magnitude F when compressed by a distance x according to
F = kx
where k is the spring constant. Solve for k :
k = F / x = (108.0 N) / (0.0191 m) = 5654.45 N/m
Now solve for F when x = 0.0440 m :
F = (5654.45 N/m) (0.0440 m) = 248.796 N ≈ 249 N

Find the time required to move from the equilibrium position directly to a point a distance 12.3 cm away.A cheerleader waves her pom-pom in SHM with an amplitude of 18.0 cm and a frequency of 0.855 Hz
The time required to move from the equilibrium position directly to a point a will be 0.879 sec.
What is the period of oscillation?The period is the amount of time it takes for a particle to perform one full oscillation. T is the symbol for it. Taking the reciprocal of the frequency yields the frequency of the oscillation.
The standard equation for the SHM is found as;
[tex]\rm x = asin \omega t \\\\ \rm 12.3 \times 10^{-2} = 18.0 \times 10^{-2}sin \omega t \\\\ 0.6833=sin \omega t \\\\ \omega t =sin^{-1}0.6833 \\\\ \omega t =0.7522 \\\\ t = \frac{0.7522}{0.855 } \\\\ t=0.879\ sec[/tex]

A laboratory experiment produces a single-slit diffraction pattern on a screen. If the slit is made narrower, the bright fringes will be:.
Answer:
fringes move farther
Explanation:
The relation between the distance between the fringes is given by
y = Dλ/d
where, D is the distance between the plane of slit and the screen
d is the width of slit, λ is the wavelength of light used.
As the slit made narrower, that means d decreases, the value of y increases, that means the fringes move farther.
