Answer:
The force will rise in direct relation to the mass of the objects
Explanation:
The gravitational acceleration remains constant. It is measured in meters per second squared or m/s². The average value is 9.81 m/s², calculated from observations made on varying surfaces. In reality, the acceleration can vary based on the geographical shape of the Earth relative to the earth's magnetic field and gravitational force.
For instance, if a single washer weighs 20 kg, with the gravity at 9.81 m/s², the weight would be:
F = ma
= 
If there are three washers, the total weight calculates as:
F = 3 * 20 * 9.81
= 588.6 N
Answer:
0.0031 m
Explanation:
y = Length of pixel = 281 μm
L = Distance to screen = 1.3 m
= Wavelength = 550 nm
d = Pupil diameter
= Angle
We have the expression
We have the expression
The pupil diameter calculates to 0.0031 m
The new charge of the ball will amount to 8x10^8C after removing 5x10^27 electrons.
Explanation:
Initially, if the sphere is electrically neutral, its charge stands at 0C.
When an electron with a charge of (-1.6*10^-19 C) is taken away, we effectively add a positive charge, leading to:
1.6*10^-19 C as the sphere's new charge.
For a total of N electrons removed, the sphere's overall charge now becomes:
N*1.6*10^-19 C.
To calculate N when:
N*1.6*10^-19 C = 8.0x 10^8 C.
We find that N is: (8.0/1.6)x10^(8 + 19) = 5x10^27 electrons.
Response:
210.3 degrees
Justification:
The total force acting on charge A is 59.5 N
Apply the x and y components of the net force to determine the direction
atan (y/x)
Answer:
Baseball mass: 
Explanation:
Circumference of a baseball is calculated using 2πr = 23 cm
Thus, the radius comes out to be 3.66 cm, which equals 
m
The mass density of the baseball matches that of a neutron or proton.
Proton mass = 
kg
Proton diameter = 
m
Proton radius = 
m
Volume of the baseball is 
Now by substituting all values into the mass per unit volume equation for the baseball, we get:
Therefore, the baseball mass amounts to
