Answer:

The gravitational force between two objects, one of mass M1 and the other of mass M2, is:

F = G*M1*M2/R^2

Where G is a constant:

G = 6.6x10^11 m^3*/(kg*s^2)

And R is the distance between the two objects.

M1 = 5.9742x10^24 kg

M2 = 7.36x10^22 kg

R = 382171 km = 382171000 m

Then the gravitational force is:

F = 6.6x10^-11 m^3*/(kg*s^2)*(5.9742x10^24 kg)*(7.36x10^22 kg)/(382171000 m)^2

F = 1.987x10^20 N

Answer:

The temperature of steel first becomes 12 MPa at a temperature of 18.65°C

Explanation:

Given that,

Diameter = 50 mm

Temperature = 15°C

Diameter = 10 mm

Stress = 12 MPa

We need to calculate the temperature of steel

Using formula of stress

[tex]stress=\alpha Y\Delta T[/tex]

Where, Y = young modulus

T = temperature

[tex]\alpha[/tex]= coefficient of linear expansion of the material

Put the value into the formula

[tex]12\times10^{6}=17.3\times10^{-6}\times190\times10^{9}\times(T_{2}-15)[/tex]

[tex](T_{2}-15)=\dfrac{12\times10^{6}}{17.3\times10^{-6}\times190\times10^{9}}[/tex]

[tex]T_{2}=3.650+15[/tex]

[tex]T_{2}=18.65^{\circ}[/tex]

We need to calculate the temperature of magnesium

Using formula of  stress

[tex]stress=\alpha Y\Delta T[/tex]

Put the value into the formula

[tex]12\times10^{6}=25.2\times10^{-6}\times45\times10^{9}\times(T_{2}-15)[/tex]

[tex](T_{2}-15)=\dfrac{12\times10^{6}}{25.2\times10^{-6}\times45\times10^{9}}[/tex]

[tex]T_{2}=10.5+15[/tex]

[tex]T_{2}=25.58^{\circ}[/tex]

Hence, The temperature of steel first becomes 12 MPa at a temperature of 18.65°C

Explanation:

Anaerobic exercise is any activity that breaks down glucose for energy without using oxygen. Generally, these activities are of short length with high intensity. The idea is that a lot of energy is released within a small period of time, and your oxygen demand surpasses the oxygen supply.

Answer:

The correct option is;

Biochemist → Archivist → Civil Engineer → Engineering Technician

Explanation:

1) Biochemist require the completion of a science degree or applied science degree, while biochemist usually hold a PhD to perform research independently, while entry level positions in the profession require a masters or bachelors degree

The PhDs usually require about 5 years to complete, after obtaining the masters degree

2) The general educational requirement to become an archivist is a master's degree in the fields of library science, history, public administration, political science, or archival science, which requires the completion of a bachelors degree followed by the completion of the masters degree which is thus 4 to 6 years

3) Civil engineer title is awarded to holders of a bachelors degree in Civil Engineering which gives the strong mathematical and science background required in the profession usually. The Civil Engineering program duration is five years

4) The engineering technician consist of 8.2% with masters degree, 42.0% have bachelors degree, while it is also possible to become an engineering technician with a GED or a high school degree

Therefore, the usual duration of study to become an engineering technician is two years of an associate degree program.

Answer:

C

Explanation:

The kinetic energy of the moving sled with the given value of mass and velocity is 7.84 × 10³ Joules.

Kinetic energy is simply a form of energy a particle or object possesses due to its motion.

It is expressed as;

K = (1/2)mv²

Where m is mass of the object and v is its velocity.

Given the data in the question;

To determine the kinetic energy of the sled, we substitute our given values into the above expression.

K = (1/2)mv²

K = (1/2) × 20kg × (28.0m/s)²

K = 0.5 × 20kg × 784m²/s²

K = 7840kgm²/s²

K = 7.84 × 10³J

Therefore, the kinetic energy of the moving sled with the given value of mass and velocity is 7.84 × 10³ Joules.

Explanation:

The current flows through the circuit will be 0.03 A. Electric current is the ratio of the voltage and the current.

Electric current is defined as the ratio of the charge flow in a given time interval. It is denoted by I. It has the unit is ampere.

The given data in the problem is;

The voltage of the batteries is,V=1.5V

The electric current is,I=?

The resistance is,R=50 Ω

From Ohm's law;

[tex]\rm V= IR \\\\ I = \frac{V}{R} \\\\ I = \frac{1.5}{50} \\\\ I=0.03 \ amphere[/tex]

Hence, the current flows through the circuit will be 0.03 A.

Answer:

The soccer discs will be change.

Explanation:

Given that,

Opposing force = 5 N

We know that,

Drag force :

Drag force is directly proportional to the square of velocity.

[tex]F_{d}\propto v^2[/tex]

[tex]F_{d}=\dfrac{1}{2}C\rho Av^2[/tex]

Where, C = drag constant

[tex]\rho[/tex] = density

A = area

v= velocity

We need to find what happen to  the soccer discs velocity

According to drag force,

If we applies a force of 5 N opposing the motion of the disc then the velocity of the soccer discs will be change.

Hence, The soccer discs will be change.
