The gravitational force between Venus and the Sun, seperated at the distance of 1.082×10¹¹ m is 5.520×10²² N.
What is gravitational force?Gravitational force is the attractive force between two bodies. It is applicable to all the bodies have masses and it is called as Universal law of gravitation.
Grarvitational force is the attractive force is directly proportional to the product of two masses and is inversely proportional to the square of distance between them.
F ∝ m₁ × m₂ / d², m₁ and m₂ is the mass of two bodies and d² is the distance between two bodies. The SI unit of mass is kg and SI unit of distance is m. The SI unit of force is newton.
From the gravitational force,
F = G (m₁×m₂ / d²)
G represents gravitational constant and is equal to 6.67× 10⁻¹¹ N.m²/kg².
From the given,
m₁ ( mass of venus ) = 4.87 x 10²⁴kg
m₂ ( mass of sun) = 1.989 x 10³⁰ kg
d² ( distance between sun and venus) = 1.082 x 10¹¹ m.
G = 6.67 ×10⁻¹¹ N.m² / kg²
F = G (m₁×m₂ / d²)
= 6.67 ×10⁻¹¹ × 4.87 x 10²⁴× 1.989 x 10³⁰ / (1.082 x 10¹¹)²
= 5.520 × 10²² N
The gravitational force between the venus and sun at the distance of 1.082 x 10¹¹ is 5.520× 10²² N.

why a small car can stop easier than an 18 wheeler while traveling at 70 mph down the interstate?
Please help me with these calculating velocity questions im so stressed out
Answer: -10m/s
Explanation:
Velocity is solved using the equation displacement over time. Part C shows a displacement or change in x of 30 and a change in time of 3 secs (7-10) so the equation would be 30m/3s= -10m/s it is negative because look at the slope. Its decreasing right? So that means the objects is slowing down which means it can't have a positive velocity

B The golf ball is equally likely to be pink, white, orange, or green.
C The golf ball is 2 times as likely to be orange as it is to be pink.
D The golf ball is 7 times as likely to be green as it is to be white.
The golf ball is two times as likely to be orange as it is to be pink. Therefore, option C is correct.
What is probability?Probability can be described as the branch of mathematics of numerical descriptions of how likely an event is to take place. The probability of an event can be a number between 0 and 1, where 0 indicates the impossibility of the event and 1 shows certainty.
Given, the number of pink balls = 4
The number of white balls = 11
The number of orange balls = 8
The number of green balls = 18
The total number of balls = 4 + 11 + 8 + 18 = 41
When Felix picks a golf ball at random. The golf ball is more likely to be pink = 4/41
The probability golf ball is more likely to be white = 11/41
The probability golf ball is more likely to be orange = 8/41
The probability golf ball is more likely to be green = 18/41
Therefore, the golf ball is two times as likely to be orange as it is to be pink.

A piece of wire length 30cm and cross sectional area of 0.5mm^2 has a resistance of 5ohms at 20°c. It is then heated to a temperature of 150°c. Calculate it's resistivity at 20°c
Answer:
8.333*10^-6 ohms
Explanation:
Resistivity of a material is expressed as;
p = RA/l
R is the resistance of the material
A is the cross sectional area
l is the length of the material
Given
R = 5 ohms
A = 0.5mm^2
A = 5 * 10^-7m^2
l = 30cm = 0.3m
Substitute into the formula;
p = (5 * 5 * 10^-7m^2)/0.3
p = 25 * 10^-7/0.3
p = 0.0000025/0.3
p = 8.333*10^-6
Hence its resistivity at 20 degrees Celsius is 8.333*10^-6 ohms
What happend to the space pod in missing seconds?
Answer:
From our investigation of what forces are like in a collision, we learned that when two
objects collide, a force is exerted on each object. The two forces are in opposite
directions but the same strength. This allowed us to infer that an equal strength force
was exerted on the space station and the pod, but in opposite directions.
As a result, the space station and the pod are moving in opposite directions. We need to
learn more about the effects of collisions on each object’s motion so we can report back
to Dr. Gonzales at the space agency.
You will use physical materials to gather data about
forces in a collision. You will also notice how objects
are affected by collisions. Students will use their
data to infer the force direction for objects in a
collision.
Based on the velocity change of each object,
what did you infer about the direction of forces
during a collision?
• We observed that the velocity of each object changed during a collision, so we can infer
that a force had to be exerted on each object. However, the motion of the objects
changed in different ways.
• The object that was moving forward slowed down, so I can infer that the force must have
pushed backward on this object.
• The other object started moving forward, so the force must have pushed forward on that
object. If one force was backward and one force was forward, then the forces pushed
the objects in opposite directions.

The atomic number is always equal to the total number of which is also equal to the total number of
Answer:
Protons; electrons.
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such defines the structure of a chemical element.
Generally, these atoms are typically made up of three distinct particles and these are protons, neutrons and electrons. All the physical properties of a mineral result from the mineral's internal arrangement of atoms.
The atomic number is always equal to the total number of protons, which is also equal to the total number of electrons. Protons are the positively charged particles that make up an atom while electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
A chemical element is denoted by [tex] X_{Z}^{A} [/tex]
Where;
X is the symbol of the element.
A is the atomic mass or number of nucleons.
Z is the atomic number or number of protons.
Therefore, the number of neutrons = A - Z
