When forces of 5 N and 7 N respectively act on an object. When will the resultant of the two vectors be at a maxium
Answer:
F = 12 N
Explanation:
Given that,
Force of 5 N and 7 N respectively act on an object.
We need to find the resultant of the two vectors be at a maximum.
Force will be maximum when two forces acts in same direction. It means we can simply add them i.e.
F = 5 N + 7 N
F = 12 N
Hence, the resultant force is 12N.
Why is it very dangerous
for the driver and
passengers if any bubbles of gas get into
the brake fluid? Even worse what would go wrong if the break fluid leaked out of its pipes?
Answer:
If it leaks....
If there is a brake fluid leak and air gets mixed with the fluid in the brake lines, then the fluid will not be able to flow correctly. As a result, when you press your foot down on the brake pedal, it will feel squishy or spongy. In other words, the brake pedal will feel very soft.
If air bubbles get into....
Air is the enemy in a hydraulic system because it reduces pressure and essentially makes the process less effective. When air gets into the brake lines, your brake system suffers. Symptoms that can indicate you have air in your brake lines include the following: Brake pedal feels spongy when you press down

Write two complete sentences for each question for a total of four complete sentences. What is the purpose of cellular respiration? How is cellular respiration similar to photosynthesis?
PLEASE HELP ME
Explanation:
The purpose of cellular respiration is the to provide energy for the body of an organism. In this process, food materials are broken down by complex metabolic actions usually with the availability of oxygen. Then, energy is liberated for use by an organism and the waste is expelled.
Cellular respiration and photosynthesis are both similar. In that they are ways by which organisms obtain nutrition. The food for plant is derived by the process of photosynthesis. Also, other organisms use this food for their own nourishment.
Newton's Law of Gravity states that if the mass of one object doubles, the gravitational pull on a second object will
____.
doubles
decreases by half of half
quadruples
decreases by half
Answer:
It will double.
Explanation:
Newton's Law of Gravity states that [tex]F_G=\frac{Gm_1m_2}{r^{2}}[/tex], where G is the gravitational constant, r is the distance between the objects' centers, and [tex]m_1[/tex] and [tex]m_2[/tex] are the objects' masses. We just have simple math here: by doubling [tex]m_1[/tex], we double the entire fraction. By doubling the entire fraction, we double the gravitational pull. Therefore, Newton's Law of Gravity states that if the mass of one object doubles, the gravitational pull on a second object will double.
I hope this helps you understand it! Have a great day, 'kay?
Answer:
It doubles.
If the mass of one of the objects is doubled, then the force of gravity between them is doubled. Since the gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
Which part of the drum vibrates when it produces sound?
Explanation:
For example, when a drum is struck, the flexible skin (sometimes called a membrane) of the drum vibrates. The compression and expansion of the air on either side of the vibrating membrane produces differences in air pressure. The pressure differences generate a sound wave that propagates outward from the drum surface.

The apple is on the tree and it is not moving. What are the two types of forces acting
on the apple?
Answer:
An apple hanging on a tree is acted upon by two basic forces: 1) the downward force exerted by the gravity force and, 2) the upward force exerted by the tree limb. The downward gravity force is also know as "weight".
The two types of forces acting on the apple on the tree are gravitational force and pressure by the wind. The gravitational force acting on it experiences as its own weight.
What is force?Force is an external agent acting on a body to change its motion or to deform it. There are various kinds of force such as gravitational force, magnetic force, nuclear force etc.
Gravitational force is the force by which an object attracts other object into its center of mass. Earth gravitationally pull all objects in its surface to the ground.
The apple on the tree will experience a force of gravitation by the earth as well as the force exerted by the air currents passing through the region.

The s.I unit of R so that the equation velocity= R × density S dimensionally correct R is a constant
Answer:
R = m⁴/kg . s
Explanation:
In this case, the best way to solve this is working with the units in the expression.
The units of velocity (V) are m/s
The units of density (d) are kg/m³
And R is a constant
If the expression is:
V = R * d
Replacing the units and solving for R we have
m/s = kg/m³ * R
m * m³ / s = kg * R
R = m * m³ / kg . s
R = m⁴ / kg . sThis should be the units of R
Hope this helps

Answer:
B.dunes
Explanation:
sand dunes are created by wind
The landform which is formed from the destructive and constructive processes of wind forces is dunes. Hence, option B is correct.
What is a landform?An anthropogenic or natural land feature on the solid surface of the Earth or another planetary body is referred to as a landform. A given terrain is made up of several landforms, and topography refers to how these landforms are arranged in the surrounding area. In addition to shoreline characteristics like bays, peninsulas, and seas, landforms also include hills, mountains, canyons, and valleys. Submerged structures like volcanoes, mid-ocean ridges, and major ocean basins are also considered to be landforms.
Physical characteristics of landforms, such as height, slope, orientation, stratification, rock exposure, and soil type, are used to classify them. Intuitive elements like berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and many more structural and size-scale elements, including different types of inland and marine waterbodies and sub-surface features, are all examples of gross physical features or landforms.

3 kids are pushing on a cart 2 are pushing north at 50 N each. The 3rd is pushing South at -90 N. The net force is _N?
Answer:
Explanation:
When two forces act in the same direction , they add up and when they act in opposite direction , they subtract .
2 forces each of 50 N act in same direction , so they will add up to give resultant force of 100 N . Now third force acts in opposite direction so 100 N and - 90 N will subtract to give total resultant force .
Resultant force = 100 - ( - 90 ) = 190 N
So net force or resultant force = 190 N .

The distance between two particles is 2 centimeters. If the distance is increased to 4 centimeters, the force will be ?
Answer:
The new force is 1/4 of the previous force.
Explanation:
Given
[tex]Initial\ Distance = 2cm[/tex] ---- [tex]r_1[/tex]
[tex]New\ Distance = 4cm[/tex] --- [tex]r_2[/tex]
Required
Determine the new force
Let the two particles be q1 and q2.
The initial force F1 is:
[tex]F_1 = \frac{kq_1q_2}{r_1^2}[/tex] --- Coulomb's law
Substitute 2 for r1
[tex]F_1 = \frac{kq_1q_2}{2^2}[/tex]
[tex]F_1 = \frac{kq_1q_2}{4}[/tex]
The new force (F2) is
[tex]F_2 = \frac{kq_1q_2}{r_2^2}[/tex]
Substitute 4 for r2
[tex]F_2 = \frac{kq_1q_2}{4^2}[/tex]
[tex]F_2 = \frac{kq_1q_2}{4*4}[/tex]
[tex]F_2 = \frac{1}{4}*\frac{kq_1q_2}{4}[/tex]
Substitute [tex]F_1 = \frac{kq_1q_2}{4}[/tex]
[tex]F_2 = \frac{1}{4}*F_1[/tex]
[tex]F_2 = \frac{F_1}{4}[/tex]
The new force is 1/4 of the previous force.
