Answer:
11.) g = 3.695 m/s^2
12.) g = 8.879 m/s^2
13.) E = 8127 N/C
Explanation:
11.) Given that the
Mercury mass M = 3.3 × 10^23kg
Radius r = 2.44 ×10^6 m
Gravitational constant G = 6.67408 × 10^-11 m3kg-1 s^-2
Gravitational field strength g can be calculated by using the formula below
g = GM/r^2
Substitutes all the parameters into the formula
g = (6.67408 × 10^-11 × 3.3 × 10^23)/(2.44×10^6)^2
g = 2.2×10^13/5.954×10^12
g = 3.695 m/s^2
12.) Given that the
Venus mass M = 4.87×10^24kg
Radius r = 6.05 × 10^6 m
Using the same formula for gravitational field strength g
g = GM/R2
Substitute all the parameters into the formula
g = (6.67408 × 10^-11 × 4.87×10^24)/(6.05×10^6)^2
g = 3.25×10^14/3.66×10^13
g = 8.879 m/s^2
13.) Given that the
Charge = 2.26 nC = 2.26×10^-9
Distance d = 0.05m
Electric field strength E can be calculated by using the formula below
E = Kq/d^2
Where
K = electrostatic constant 8.99 × 10^9 Nm2/C2
Substitutes all the parameters into the formula
E = (8.99 × 10^9 × 2.26×10^-9)/0.05^2
E = 20.3174/2.5×10^-3
E = 8126.96 N/C

Answers
Answer: Concave mirror and convex lens
Explanation: A spherical mirror and a thin spherical lens have each a focal length of +10cm, this means that distance of any object from the mirror is +10 metres.
While for the lens, the distance of any object to the other side of the lens is +10 metres. Therefore, the mirror is concave mirror and the lens is a convex lens.
A vector points 12.0 units along the x-axis, and 9.00 units along the y-axis. Find the direction of the vector
Answers
The resultant points somewhere between the positive x and y axes.
The angle it makes with the x-axis has a tangent of (9/12) = 0.75 .
That angle is 36.9°, rounded to the nearest tenth of a degree.
So the resultant vector points up and to the right, 36.9° above the x-axis.

If a (hypothetical) atom with 30 protons and 44 neutrons undergoes alpha decay:
how many protons will be left in the nucleus?
how many neutrons will be left in the nucleus?
Answers
Answer:
Protons = 28
Neutrons = 42
Explanation:
Alpha decay is one of radioactive decay in which the atomic nuclei can be illustrated by the emission or loss of helium particles of mass number 4 and proton number of 2
Because mass number is the sum of protons and neutrons, If a (hypothetical) atom with 30 protons and 44 neutrons undergoes alpha decay, 28 protons will be left in the nucleus and 42 neutrons will be left in the nucleus.

3.If a force of 12 N is applied to an object with a mass of 2 kg, what will be its acceleration?
Answers
Answer:
6 m/s^{2}
Explanation:
The formula for force is
F = mass x acceleration
F = 12 N
mass = 2 kg
So, you can change the formula to solve for acceleration.
acceleration = F / mass
a = 12 N / 12 kg
a = 6 m/s^{2}

Which of the following is the best description of the term resultant
displacement?
A. The scalar that joins all the points along the path.
B. The average of all the displacement vectors.
C. The total distance traveled.
O D. The shortest distance from the beginning point to the end point.
Answers
Answer:
D
Explanation:
Displacement refers to the shortest, or straight-line path from one point to another. It is a vector, thus A is incorrect. It is not the average, but rather the sum of all displacement vectors, so B is incorrect. It is not the distance traveled, as some paths have longer distances than others, while leading to the same destination, hence same displacement. (i.e. running around in circles yields positive distance traveled but zero displacement.)
Answer:
Explanation: D
Displacement is a vector. It has direction and it has magnitude. But we are asked for the resultant displacement. You have to use pythagorean theorem. This makes our answer always positive. That essentially means distance, since you did just do the distance formula.
A is wrong because that tells you perimeter
B is wrong because that tells you the midpoint
C is wrong because displacement and distance are two different things. We dont want the distance of the two vectors
D is correct, this perfectly explains the distance formula

Answers
Explanation:

(B) 1.58 x 105 in
(C) 4.02 x 103 km
(D) 4.40 x 103 yd
(E) 4.02 x 105 cm
Answers
Answer:
Choice C is not equivalent to 2.50 miles.
Explanation:
The given data is now converted into feet, inches, kilometers, yards and centimeters:
mi - ft
[tex]x = (2.50\,mi)\cdot \left(5280\,\frac{ft}{mi} \right)[/tex]
[tex]x = 13200\,ft[/tex]
[tex]x = 1.320\times 10^{4}\,ft[/tex] (Choice A)
mi - in
[tex]x = (2.50\,mi)\cdot \left(5280\,\frac{ft}{mi} \right)\cdot \left(12\,\frac{in}{ft} \right)[/tex]
[tex]x = 158400\,in[/tex]
[tex]x = 1.584\times 10^{5}[/tex] (Choice B)
mi - km
[tex]x = (2.50\,mi)\cdot \left(1.61\,\frac{km}{mi} \right)[/tex]
[tex]x = 4.025\,km[/tex] (Different from Choice C)
mi - yd
[tex]x = (2.50\,mi)\cdot \left(5280\,\frac{ft}{mi}\right) \cdot \left(\frac{1}{3}\,\frac{yd}{ft} \right)[/tex]
[tex]x = 4400\,yd[/tex]
[tex]x = 4.40\times 10^{3}\,yd[/tex] (Choice D)
mi - cm
[tex]x = (2.50\,mi)\cdot \left(1.61\,\frac{km}{mi} \right)\cdot \left(100000\,\frac{cm}{km}\right)[/tex]
[tex]x = 402500\,cm[/tex]
[tex]x = 4.025\times 10^{5}\,cm[/tex] (Choice E)
Choice C is not equivalent to 2.50 miles.

At which point is the potential energy the greatest? At which point is kinetic energy the greatest?
Answers

Kinetic energy is greatest at the lowest point of a roller coaster and least at the highest point.
hope it helps you make me as brainlylistPotential energy will be greatest at the points A and G, and kinetic energy will be greatest at the point D.
• The energy possessed by an object due to its motion is termed as the kinetic energy. On the other hand, the energy stored within an object because of its position relative to some zero position is known as the potential energy of the object.
• Kinetic energy is highest when the velocity is the highest, in the case of pendulum, this takes place at the bottom. In the given case, that is, at point D.
• If kinetic energy is highest at point D, then at the same point potential energy will be the lowest.
• Therefore, potential energy would be highest at its highest point on each of the side of its motion where it remains stationary for some time, that is, at point G and A.
Thus, kinetic energy would be highest at point D, and potential energy would be highest at the points A and G.
