Answer:

The average acceleration is about 8.51 m/s

Explanation:

     We can use the formula for acceleration to solve.

a = [tex]\frac{velocity_{final} -velocity_{start} }{time}[/tex]

a =  [tex]\frac{80-0}{9.4}[/tex]

a =  [tex]\frac{80}{9.4}[/tex]

a ≈ 8.51

We know that:

[tex]0.5m(vB^{2} -vA^{2} )=q*[VB-VA]\\== > vB^{2} =vA^{2} +(\frac{2q}{m})*[VB-VA]\\ =(4.30*10^{4} )^{2} +(\frac{2*1.6*10^{-19} }{2*1.67*10^{-27} }) [-10-30]\\[/tex]

[tex]=18.49*10^{8} -76.64*10^{8}[/tex]

[tex]=-58.15*10^{8} \\== > vB=-7.62*10^{4} m/s[/tex]

The proton's speed at point B is  -7.62 x ×10⁴ m/s.

The proton is a subatomic particle lies inside the nucleus of an atom of element. The number of proton gives an idea of the atomic number of the element.

The proton's speed as it passes point A is 4.00×10⁴ m/s . It follows the trajectory shown.

1/2m (vb² - va²) = q (Vb - Va)

vb² =  va² +2q/m (Vb - Va)

where v is the velocity and V is the potential at point A and B, q ia the charge on proton and m is the mass of proton.

Substitute the given values, we get

vb² = (4.00×10⁴ ) + (2x1.6 x 10⁻¹⁹/1.67 x 10⁻²⁷) (-10 - 30)

vb = -7.62 x ×10⁴ m/s

Thus, proton's speed at point B is  -7.62 x ×10⁴ m/s.

Answer:

A

Explanation:

I took the quiz

Because when we polish the shoes, they gain charges or the shoes become charged, the small non-charged particles are attracted to them.

Answer:

a=650.549

b=246.4819

c=38.5261

Explanation:

Answer:

The molecules form strong hydrogen bonds, and water has a correspondingly high latent heat of vaporization. When no strong bonds are present, heating a liquid can easily free the molecules to form a gas, and the latent heat of vaporization is low.

Explanation:

Which of the diagrams shows the least gravitational force between the two objects?

a. I

b. II

c. III

d. IV

From above observation we can conclude that gravitational force is least in 4th case because we have less mass on both side and we have more distance between the 2 masses that others with same mass .

Answer:

D if I'm incorrect then sorry.

Answer: I am so sorry i hadn't learned this Yet~!

Explanation:

Answer:

Gravitational force is the force that attracts objects towards each other. Two factors that affect the gravitational force between objects are the mass of the two objects and the distance between

Explanation:

Gravity is what pulls us towards the Earth if we were to jump into the air, so it is the force that pulls things towards other things. The bigger the objects are the more gravity they have, so a planet has more gravity than say, an apple. Distance between objects also makes their gravity change, so the Earth's pull on the moon is different than the Earth's pull on the sun.

Hi there!

We can begin by using Lenz's Law:
[tex]\epsilon = -N\frac{d\Phi _B}{dt}[/tex]

N = Number of Loops

Ф = Magnetic Flux (Wb)
t = time (s)

Also, we can rewrite this as:
[tex]\epsilon = -NA\frac{dB}{dt}[/tex]

A = Area (m²)

Since the area is constant, we can take it out of the derivative.

This is a single wire loop, so N = 1.

Now, we can develop an expression for the induced emf.

We can begin by solving for the area:

[tex]A = \pi r^2 \\\\d = r/2 r = 0.05cm \\\\A = \pi (0.05^2) = 0.007854 m^2[/tex]

We can also express dB/dt as:
[tex]\frac{dB}{dt} = \frac{\Delta B}{t} = \frac{0-0.5}{t} = \frac{-0.5}{t}[/tex]

Now, we can create an equation.

[tex]\epsilon = -(1)(0.007854)\frac{-0.5}{t} = \frac{0.003927}{t}[/tex]

To solve the system, we must now develop an expression for current given an emf and resistance.

Begin by calculating the resistance of the copper wire:
[tex]R = \frac{\rho L}{A}[/tex]

ρ = Resistivity of copper (1.72 * 10⁻⁸ Ωm)
L = Length of wire (0.01 m)

A = cross section area (m²)

Solve:
[tex]R = \frac{(1.72*10^{-8})(0.01)}{\pi (0.001^2)} = 5.475 * 10^{-5} \Omega m[/tex]

Now, we can use the following relation (Ohm's Law):

[tex]\epsilon = iR\\\\\epsilon = \frac{Q}{t}R[/tex]

*Since current is equivalent to Q/t.

Plug in the value of R and set the two equations equal to each other.

[tex]\frac{Q}{t}(5.475 * 10^{-5}) = \frac{0.003927}{t}[/tex]

Cancel out 't'.

[tex]Q (5.475 * 10^{-5}) = 0.003927 \\\\Q = \frac{0.003927}{5.475*10^{-5}} = \boxed{71.73 C}[/tex]

[tex]\text{Weight ,} W = mg = 150 \times 9.8 =1470N[/tex]

Explanation:

f=ma

where force is weight. we know that a is the acceleration of gravity which is -9.8 m/s^2

so f is

-1471.5 N

This is defined as the rate of change of position of an object with respect to time. The unit is metres per second(m/s).

Velocity = distance/ time

The velocity for column 1 = 500m/7.4s = 67.57m/s.

The velocity for column 2  = 500m/6.4s = 78.13m/s.

convection is the answer

The process that describes the warm ocean that transfers heat to the air above it is known as Convection. Thus, the correct option for this question is B.

Some characteristics of heat are as follows:

The process of convection transfers heat with the help of the migration of a fluid (liquid or gas) between areas of different temperatures. It is an approach that signifies the transfer of heat between two bodies by involving currents of moving gas or fluid.

Therefore, convection is the process that describes the warm ocean that transfers heat to the air above it. Thus, the correct option for this question is B.
