The galaxy that contains our solar system, the milky way, is approximately a uniform disc of mass 10^12Msun and diameter 175×10^3 light years. Assuming that the center of mass of the galaxy is at rest, estimate the time that it takes the sun to complete one orbit around the galaxy center. A few useful numbers: the mass of the sun Msun = 2 × 10^30kg, 1 light year = 9.46 × 10^15m, and the distance between the sun and the galaxy center d = 26.4 × 10^3 light years.

Use the viral relation PE = -2 KE, and estimate the period using, t=2pir/v

If the mass of the ice in the test tube is
m_ice=15g
mass of warm water used (g) = 70g
Initial temperature of water (in degrees C ) =70C
Equilibrium temperature of ice-water system (in degrees C) =44C
Calculate the calories of energy required to melt one gram of ice.

The cube in the figure below has 5 sides grounded and the other side is held at a potential Vo. What is the potential at the center of the cube?

Side note: I can't upload the image for some reason. All it shows is a cube with a shaded face on the right hand with an arrow pointing left into that shaded side, with the label Vo.

Two charges each +q are initially separated by a distance d. If you triple the distance, the magnitude of the force does what?

A 750-g disk sliding along frictionless ice with a speed of 8.5 m/s strikes a stationary rod-disk combo 12-cm from its center-of-mass. This rod-disk combo is made from a 360-g rod that is 35-cm long, with 2 150-g solid disks of radius 7.0-cm attached, one on each end of the rod. After the perfectly elastic collision, the disk moves off along a path that is 28º above its original path, while the rod-disk combo spins about its center-of-mass as it moves off at an angle as well. Using this information, find the translational speed of both objects after the collision, the angular speed of the rod-disk combo, and the angle of its trajectory.

Explain the Enzyme-Based sensors for the assay of glucose. Discuss the reaction mechanism too. Explain in detail working principle with the chemical reactions involved in this measurement.

The acceleration of a 5.00 kg object (a box) is described below.

From t=0 to 10.00 seconds, the acceleration is time-dependent and is given by the formula: a=(0.200 m/s^3) t

From time t= 10.00 up to t=15.00 seconds, the acceleration of a box is constant and is given by the following formula: a=2.00 m/s^2

From t=15.00 up to t=25.00 seconds, the acceleration is given by a=(-0.200 m/s^3)t+5.00 m/s^2

Produce a single graph (of Force vs. time) in Excel that illustrates this. Your data should start at t=0 and go up to t=25.00 in increments of 1.00 seconds.

After you have produced the graph, calculate the impulse (J) from the graph. Note that the impulse is the area under a force v. time graph curve.

Impulse= _______ kg m/s

Assume that the speed of the ball is what you found the in previous question. What is the tension force in the rope when the ball is the bottom of its circular path? Enter you answer in multiples of (mg).

For example, if you find the tension force is  you should enter 3.75 as you answer.

My speed was 3.13 m/s - marked correct. the Radius is 1m.

The answer is not 1.32 - as previously answered on another question.

A professional boxer hits his opponent with a 1345-N horizontal blow that lasts for 0.122 s.

a) Calculate the impulse (in kg · m/s) imparted by this blow.

b) What is the opponent's final velocity (in m/s), if his mass is 113 kg and he is motionless in midair when struck near his center of mass?

c) Calculate the recoil velocity (in m/s) of the opponent's 11.4 kg head if hit in this manner, assuming the head does not initially transfer significant momentum to the boxer's body.
