Explain Newton's Law Of Gravity, and explain how the formula works correctly and combines mathematical arithmetic to figure out gravity.
Answer:
Explanation:
Newton's Law Of Gravity states two masses will have an attraction force that is proportional to their masses and inversely proportional to the square of their separating distance.
Mathematically it is expressed as Force = G * M1 * M2 / d^2 where
G is the gravitational constant, M1 and M2 are the masses and d is the separating distance.

An object's velocity increases, multiplied by a factor of 9. What factor would its Kinetic Energy increase by?
Answer:
by 81
Explanation:
KE = (1/2)mv^2. If v2 ---> 9v then
KE2 = (1/2)m(9v)^2 = 81[(1/2)mv^2]
= 81 KE
Answer:
by a factor of 4
Explanation:
The kinetic energy is proportional to the square of the speed so doubling the speed increases.
After rubbing the hair on your head with a balloon, you determine there are 2.4 x 1018 electrons on your head. What is the charge, in coulombs (C), of your head?
Answer:
q = 0.384 C
Explanation:
The total charge present at the head can be easily found out by multiplying the charge on a single electron with the total number of electrons present on the head:
[tex]q = ne[/tex]
where,
q = total charge on head = ?
n = total no. of electrons on the head = 2.4 x 10¹⁸
e = charge on 1 electron = 1.6 x 10⁻¹⁹ C
Therefore,
[tex]q = (2.4\ x\ 10^{18})(1.6\ x\ 10^{-19}\ C)[/tex]
q = 0.384 C

While performing a stunt, Danger Dog rides his motorcycle off the edge of a cliff with a velocity of 32 m/s. If the cliff is 45 m high, how far from the base of the cliff will Danger Dog land? Enter your answer in meters. 11 m 96 m 288 m 4 m
Answer:
The correct answer is b: 96 m.
Explanation:
The total distance in the horizontal direction traveled by Danger Dog can be calculated using the following equation:
[tex] x_{f} = x_{0} + v_{0_{x}}t + \frac{1}{2}at^{2} [/tex] (1)
Where:
[tex] x_{f}[/tex]: is the final position in the horizontal direction =?
[tex]x_{0}[/tex]: is the initial position in the horizontal direction = 0
[tex] v_{0_{x}} [/tex]: is the initial velocity in the horizontal direction = 32 m/s
t: is the time
a: is the acceleration = 0 (he is accelerated only by gravity)
So, we need to find the time. We can find it as follows:
[tex] y_{f} = y_{0} + v_{0_{y}}t - \frac{1}{2}gt^{2} [/tex] (2)
Where:
[tex] y_{f}[/tex]: is the final position in the vertical direction = 0
[tex]y_{0}[/tex]: is the initial position in the vertical direction = 45 m
[tex] v_{0_{y}} [/tex]: is the initial velocity in the vertical direction = 0
g: is the acceleration due to gravity = 10 m/s²
By solving equation (2) for "t" we have:
[tex] t = \sqrt{\frac{2(y_{0} - y_{f})}{g}} = \sqrt{\frac{2*45 m}{10 m/s^{2}}} = 3 s [/tex]
Hence, the total distance traveled by Danger Dog in the x-direction is (equation 1):
[tex] x_{f} = 32 m/s*3 s = 96 m [/tex]
Therefore, the correct answer is b: 96 m.
I hope it helps you!

The angular velocity is the ration of the change in the angle turned to time.
Why does the angular velocity increase?The angular velocity is the ration of the change in the angle turned to time. As such, the angular velocity is measured in radians per second. We have been told that the athlete is supposed to perform the jump between figures 1 and 2 in multiple somersaults.
Each time the athlete somersaults, the angular velocity changes. As such, the rate of change of the angular velocity between figures 1 and 2 would be quite high.
On the other hand, the athlete jumps straight vertically down between figures 2 and 3 and does not turn. Hence, the angular velocity decreases.

In 1993, the gold reserves in the United States were about 8.490 × 106
kg. If all
that gold were made into a thick wire with a cross-sectional area of 1cm2
, its
total resistance would be about 6.60 × 102 Ω. If the same operation were
applied to the gold reserves of Germany, France, and Switzerland, the
resistances would be 2.40 × 102 Ω, 2.00 × 102 Ω, and 2.00 × 102 Ω,
respectively. Now consider all four resistors connected as shown in the circuit
diagram below. Find the equivalent resistance.
The equivalent resistance of the circuit is 65.98 Ω.
What is Resistor?
A resistor is an electrical component that limits or regulates the flow of electrical current in a circuit. It is designed to provide a specific amount of resistance to the flow of electrons, measured in ohms, and is typically made of a material that can resist the flow of electricity, such as carbon or metal. Resistors are used in a wide range of electronic devices and circuits, from simple LED flashers to complex computer systems.
To find the equivalent resistance of the circuit, we need to use the formula for resistors in parallel:
1/Req = 1/R1 + 1/R2 + 1/R3 + 1/R4
where Req is the equivalent resistance, and R1, R2, R3, and R4 are the resistances of the four resistors.
Substituting the given values, we get:
1/Req = 1/6.60 × 102 + 1/2.40 × 102 + 1/2.00 × 102 + 1/2.00 × 102
1/Req = 0.01515
Req = 65.98 Ω
Therefore, the equivalent resistance of the circuit is 65.98 Ω.

7. Telescope efficiency depends on the area of the primary mirror, while angular resolution scales as 1/D, where D is the diameter of the telescope. State which is true concerning the objects observed with a 30m telescope, versus a 10m telescope. A) The 30 m telescope can observe objects 30 times fainter, and with 3 times the resolution of the 10 m telescope. B) The 30 m telescope can observe objects with 1/9 the angular diameter, and 9 times fainter than, the 10 m telescope. C) The 30 m telescope can observe objects 9 times fainter, and with 3 times smaller angular size, than the 10 m telescope. D) The 30 m telescope can observe objects 3 times fainter, and with 3 times smaller angular size, compared to the 10 m telescope.
Answer:
Option C, The 30 m telescope can observe objects 9 times fainter, and with 3 times smaller angular size, than the 10 m telescope.
Explanation:
As we know,
The surface brightness of the object viewed through telescope is proportional to the square of the diameter of the lens
Thus, Brightness ([tex]B_{30}[/tex]) of 30 m telescope would be proportional to [tex]30^2[/tex]
Brightness of 10 m ([tex]B_{10}[/tex]} telescope would be proportional to [tex]10^2[/tex]
Thus, the ration of the two would be
[tex]\frac{B_{30}}{B_{10}} = \frac{30^2}{10^2} \\\frac{B_{30}}{B_{10}} = \frac{9}{1} \\B_{30} = 9 * B_{10}[/tex]
Thus, brightness of 30 m telescope would be able to view 9 times fainter object as compared to the 10 m telescope.
Also , 30 m telescope would be able to view 3 times smaller angular sized object as compared to the 10 m telescope
Hence, option C is correct

7. A train 100 m long is moving with the velocity of 72 km/h. Find the time it takes to cross the bridge which is 2 km long?
a) 1050 S
b) 10500 s
c) 10.5 s
d) 105 s
Answer:
d) 105 s
Explanation:
Given the following data;
Distance A (length of train) = 100 m
Velocity = 72 km/h to meters per seconds = 72 * 1000)/3600 = 72000/3600 = 20 m/s
To find the time;
Time = distance/speed
Time = 100/20
Time = 5 seconds.
II. When the distance (bridge) is 2km;
Distance B = 2km = 2*1000 = 2000 meters
Time = distance/speed
Time = 2000/20
Time = 100 seconds
Therefore, total time = 5 + 100 = 105 seconds
A gas mixture has 10% O2, 50% Ar (40 gmw) and 40% Pu (244 gmw). What is the density of this mixture?
Answer: 5.39g/L
Explanation:
We need to calculate the average molar mass of the mixture which will be:
= (10 × 32) + (50 × 40) + (40 × 244) / 100
= (320 + 2000 + 9760) / 100
= 12080 / 100
= 120.8g/mol
Since the volume occupied is 22.4L and 1 mole of the gas will occupies 22.4L given the standard temperature conditions, then the density of the mixture will be:
= Mass / volume
= 120.8 / 22.4
= 5.39g/L
Therefore, the density of the mixture will be 5.39g/L.
