Which diagram represents diffuse reflection?

Answer:

C. Mass of object 1 = 12 kg

Mass of object 2 = 12 kg

Distance between objects = 1.5 m

Explanation:

From the universal gravitation equation

Force of gravity between two objects is directly proportional to the product of mass 1 and mass 2 and inversely proportional to the square of the distance apart

Option B is has the greatest factor

Force of gravity between the objects = (15 x 12)/(0.5)^2

Force of gravity between the objects = 720G

Option C has the least factor and the answer

Force of gravity between the objects = (12 x 12)/(1.5)^2

Force of gravity between the objects = 64G

G = The constant of proportionality = 6.673 x 10-11 N m^2/kg^2

The weight is equal to 'mg' where m is the mass and the g is the gravitational constant on that certain planet

In this case, the mass is 150 kg and the gravitational constant is about 9.8.

so the weight = 150 * 9.8 = 1470 Newtons.

Hope that helped!

The weight of the box with the given mass on Earth is 1470 Newtons.

Given the data in the question;

Weight is the force acting on the mass of a particular object or particle due to gravity. It is the gravitational force acting on an object with mass. It is measured in newtons. It is expressed as;

[tex]W = m * g[/tex]

Where m is mass of object and g is acceleration due to gravity on earth ( [tex]g = 9.8m/s^2[/tex] )

To find the weight of the box, we substitute our values into the expression above;

[tex]W = 150kg * 9.8m/s^2\\\\W = 1470kgm/s^2\\\\W = 1470N[/tex]

Therefore, the weight of the box with the given mass on Earth is 1470 Newtons.

Answer:

"F = 52.93 [N]

Since the Rock is thrown upwards, there are only two forces, one is the force of the rubber (55[N]) and the other is the force of gravitational acceleration acting in the opposite direction to the movement of the rock, therefore this acceleration will be taken as negative.

F = 55 - m*g

where:

F = total force [N] (units of Newtons)

m = mass = 0.21 [kg]

g = gravity acceleration = 9.81 [m/s²]

F = 55 - (0.21*9.81)

F = 52.93 [N]"

Answer:

Momentum change of the rock = 3835 kgm/s

Chane in earth's velocity = 6.4 x 10⁻²² m/s

Explanation:

m = 50.0 kg, M = 6.0 x 10²⁴ kg

d = 300.0 m

final velocity of rock = v, v² = 2gd = 2 * 9.81 * 300, so v = 76.7 m/s

Momentum change of the rock = mv = 50.0 * 76.7 = 3835 kgm/s

Inital momentum of the rock+earth system = 0

final momentum = 0 (momentum conservation)

momentum of rock and momentum of earth are same magnitude and opposite directions.

mv - MV = 0

Chane in earth's velocity = mv/M = 3835/(6.0 x 10²⁴) = 6.4 x 10⁻²² m/s

Answer:

25 J

Explanation:

Using Law of Conservation of Energy

Total Energy before = Total Energy After

Potential Energy1 + Kinetic Energy1 = Potential Energy2 + Kinetic Energy2

Potential Energy1 + 0 = 0 + Kinetic Energy2

Potential Energy1 = [tex]\frac{1}{2}*m*v^{2}[/tex] =0.5*0.5*10*10= 25 J

What is the difference between the fourth harmonic and the nth harmonic?

The fourth harmonic has frequency f4= v/λ4= 4v/2L = 4f1, and, to generalise, The nthharmonic has frequency fn= v/λn= nv/2L = nf1. All waves in a string travel with the same speed, so these waves with different wavelengths have different frequencies as shown.

We can say that having a testing site such as the mars yard helps scientists to test previously theoretical knowledge in a realistic environment.

Testing sites help scientists by providing a realistic place to test knowledge that may have previously been only theoretical through performing experiments on such test sites. This is of vital importance in the detection of errors in order to achieve a successful future mission.

Therefore, we can confirm that having a testing site such as the mars yard helps scientists to test previously theoretical knowledge in a realistic environment.

Explanation:

Compared to RNA and DNA backbone, protein backbone has a relatively simple chemical structure - a nitrogen atom, two carbon atoms, one or two oxygen atoms, and a few hydrogens.

Answer:

1 mile = 1609 meters

10 miles = 16090 meters

16090m/(24.0m/s) = 670s

16090m/(30.0m/s) = 536s

Average Speed = Total distance/Elapsed time

Average Speed = [16090m(2)]/(670s+536s) = 32080m/1206s = 26.7m/s

(a) The car's average speed is less than 27.0m/s

(b) The car's average speed is 26.7m/s
