The object's charge is 1.35 μC. The electric field strength is calculated to be 3.375 x 10^11 N/C using the formula for electric field strength.
To solve for the object's charge, we can use the formula for electric field strength:
Electric field strength = charge / distance^2
First, we need to convert the distance from centimeters to meters:
2.0 cm = 0.02 m
Plugging in the given values:
270,000 nC = 270,000 x 10^-9 C (converting from nanocoulombs to coulombs)
Electric field strength = 270,000 x 10^-9 C / (0.02 m)^2
Electric field strength = 3.375 x 10^11 N/C
Now we can rearrange the formula to solve for charge:
charge = electric field strength x distance^2
charge = (3.375 x 10^11 N/C) x (0.02 m)^2
charge = 1.35 x 10^-6 C
Therefore, the object's charge is 1.35 microcoulombs (μC).
Answer: The object's charge is 1.35 μC. The electric field strength is calculated to be 3.375 x 10^11 N/C using the formula for electric field strength. To solve for the object's charge, we rearranged the formula and substituted in the given values. The units for charge are coulombs (C), which we converted from the given value in nanocoulombs. The distance was converted from centimeters to meters to match the units of the formula.

A car drives 40 km due east and then 50 km due west .what is the cars overall displacement?
Answer:10 km westExplanation:he go 40 east then 50 west 50-40 is 10 so he displaces 10 km and as west is more than east in terms of km so we will say that it's 10 km west pls mark as brainliest thanks
The car's overall displacement if, A car drives 40 km due east and then 50 km due west is 10 km in the west.
What is displacement?Displacement is defined as the overall alteration of an object's location and motion direction. Displacement is recognized as a vector quantity since it takes into account both the direction of the motion and the magnitude of the changing position. Displacement may be zero, positive, or negative.
Given:
A car drives 40 km due east and then 50 km due west,
Consider the west direction as positive and the east direction as negative, then,
The displacement = Displacement in the west + displacement in the east,
The displacement = 50 - 40
The displacement = 10
As the sign is positive, then the direction would be west.
Thus, the displacement of the car is +10 km.

if the charge of the force is doubled would the force double
Answer: The electrostatic force between two point charge particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. So, if you double the individual charges while keeping the same distance, the net electrostatic force will be four times the previous value.
Explanation:
Since, we know
F = (k×q1×q2)/r²
When the charges are doubled, we have :
F' = (k × 2q1 × 2q2)/r²
F' = 4 (k×q1×q2)/r²
Thus,
F' = 4F
Hence, the force becomes 4 times its initial value.

A ball dropped and accelerates downwards at a rate of 10m/s^2 for 15 seconds how much will the balls velocity increase
Answer:
v = 150 m/s
Explanation:
Given that,
The acceleration of the ball, a = 10 m/s²
Time, t = 15 s
We need to find the increase in ball's velocity. When it is dropped its initial velocity is equal to 0. Let v be the velocity,
v = u+at
v = 0 +10(15)
v = 150 m/s
So, the ball's final velocity is 150 m/s.

Answer:
It will apply the greatest pressure of an area of 1.
Explanation:
To find pressure use the formula P = F/A
P = 100/1
P = 100
Answer:
10 N / cm^2
Explanation:
The Formiula is P = F / A
P = presure
F = Force in Newtons
A = area.
The answer is the smaller the area the larger the pressure.
The smallest area you have given us is 10 cm^2
The Pressure = 100N / 10 cm^2
Pressure = 10 N/cm^2

Will the gravitational force between 2 objects increase or decrease if the distance between them decreases.
Answer:
increase
Explanation:
The formula for the gravitation for of attraction is:
[tex]F = \dfrac{Gm_1m_2}{r^2}[/tex]
It implies that the force of attraction is inversely proportional to the square of the distance. i.e.
[tex]F \infty \dfrac{1}{r^2}[/tex]
where;
G = gravitational constant
m = mass; &
r = distance between the two objects.
Now let's assume that the distance between is reduced from 1 to half;
Then:
[tex]F \infty \dfrac{1}{\Big (\dfrac{r}{2} \Big)^2}[/tex]
[tex]F \infty \dfrac{4}{r^2}[/tex]
Thus, the new gravitational force of attraction increased by a factor of 4.
If there is zero total force acting on the refrigerator, the refrigerator would
A) slow down
B) speed up
C) remains the same speed
D) slow down, change direction and then speed up going the other way
E) remains at the same speed, but changes direction
Answer:
c
Explanation:
this is because newton's first law of motion states that every object will continue in its state of rest or uniform motion in a straight line unless a resultant force acts on it
so if the resultant force on the refrigerator is 0N, but it was initially moving, it will continue in its motion in a straight line.
it will not change direction since it will continue in its uniform motion.

An atom of a certain element has 36 protons, 36 electrons, and a mass number of 84. At room temperature, this element is a very stable gas. How many neutrons are in this atom?
Answer:
12 neutrons
Explanation:
The number of protons also shows the atomic number. Therefore the element in question is Krypton (Kr), which also is a noble gas.
Neutrons = Mass number - protons - electrons
Here neutrons = 84 - 36 - 36 = 12
