Answer:

Our planet's rotation produces a force on all bodies moving relative to theEarth. Due to Earth's approximately spherical shape, this force is greatest at the poles and least at the Equator. The force, called the "Coriolis effect," causes the direction of winds and ocean currents to be deflected.

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

I believe the correct answer is 30m/s/s

Answer:

The closest choice to the answer is 34.0 m

Explanation:

Projectile Motion

It's the type of motion experienced by an object that is launched near the Earth's surface and moves along a curved path exclusively under the action of gravity.

Being vo the initial speed of the object, θ the initial launch angle, and g=9.8m/s^2 the acceleration of gravity, then the Range or maximum horizontal distance traveled by the object is:

[tex]\displaystyle d={\frac {v_o^{2}\sin(2\theta )}{g}}[/tex]

The football is kicked at an angle of 30° with an initial velocity of 20 m/s. Replacing those values:

[tex]\displaystyle d={\frac {20^{2}\sin(2\cdot 30^\circ)}{9.8}}[/tex]

[tex]\displaystyle d={\frac {400\sin(60^\circ)}{9.8}}=35.35\ m[/tex]

The closest choice to the answer is 34.0 m

Explanation:

The surface which is the locus of all points which are at the same potential is known as the equipotential surface.

The surface which is the locus of all points which are at the same potential is known as the equipotential surface.In other words, any surface with the same electric potential at every point is termed as an equipotential surface.

Answer:

Explanation:

a )

initial velocity u = 45 m/s

acceleration a = - 5 m/s²

final velocity v = 0

v = u - at

0 = 45 - 5 t

t = 9 s

b )

s = ut - 1/2 at²

= 45 x 9 - .5 x5x 9²

405 - 202.5

202.5 m

2 )

a )

s = ut + 1/2 a t²

u = 0

s = 1/2 at²

= .5 x 9.54 x 6.5²

= 201.5 m

b )

v = u + at

= 0 + 9.54 x 6.5

= 62.01 m / s

3

a )

acceleration = (v - u) / t

= (34 - 42) / 2.4

= - 3.33 m /s²

b )

v² = u² - 2 a s

34² = 42² - 2 x 3.33² s

s = 27.41 m

c )

Average velocity

Total displacement / time

= 27.41 / 2.4

= 11.42 m /s

4 )

a )

v = u + at

v = 0 + 3 x 4

= 12 m /s

b )

s = ut + 1/2 a t²

= o + .5 x 3 x 4²

= 24 m

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.

Inside an atom, the strongest force is the Strong Nuclear Force, indicated by option A.

The strong nuclear force is one of the fundamental forces of nature and plays a crucial role in binding the subatomic particles, specifically protons and neutrons, within the atomic nucleus.

The strong nuclear force is responsible for overcoming the electrostatic repulsion between positively charged protons in the nucleus. It acts over extremely short distances, on the order of femtometers (10^-15 meters), and is characterized by its strength and short range. It is about 100 times stronger than the electromagnetic force, which is responsible for the interaction between charged particles.

The electromagnetic force, option B, is the second strongest force inside an atom. It is responsible for the interaction between charged particles, such as electrons and protons. The electromagnetic force is involved in holding the electrons in orbit around the nucleus and determines the chemical properties of atoms.

Gravity, option C, is the weakest force among the fundamental forces. While gravity plays a significant role on a macroscopic scale, such as the gravitational attraction between planets or objects on Earth, its influence at the atomic level is negligible compared to the strong nuclear and electromagnetic forces.

The weak nuclear force, option D, is another fundamental force, but it is responsible for processes such as radioactive decay and neutrino interactions. While it is involved in certain nuclear reactions, it is not as strong as the strong nuclear force.

In summary, the strong nuclear force is the strongest force inside an atom, overcoming the electrostatic repulsion between protons and binding the atomic nucleus together. Option 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.

Answer:

I =V/R

I= 160/20 = 8 Amperes

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
