wat is the difference between resultance and equilibrum
Explanation:
A resultant force is the sum of the forces on an object.
Forces are said to be in equilibrium when the resultant force is zero. This means the object will not accelerate.
NEED HELP ASAP What are the lengths of the x and y components of this vector?
Explanation:
the lengths of the x and y components of the vector :
the x- Component:
Vx = 12×cos72° = 12× 0.3090 = 3.708
the y-component:
Vy = 12×sin72° = 12× 0.9510 = 11.412
-
x-component
= 12 . cos 72
= 12 . 0,3090
= 3,708
y component
= 12 . sin 75
= 12 . 0,9510
= 11,412

A student wants to try to convince her parents to stop serving peas for dinner. She lays out her argument that peas are high in fructose, which is a type of sugar. Which test could she use to provide scientific evidence to support her argument that peas are high in fructose?(1 point)
brown paper bag test
vinegar test
Benedict’s test
iodine test
Answer:Benedict’s Test
Explanation:
The student will use Benedict's test to support her argument.
The common reagents for testing carbohydrates are iodine and Benedicts test.
While iodine gives a positive result with starch, it doesn't react with fructose.
Benedict's reagent is used to determine the presence of reducing sugar in a given solution.
A positive test with Benedict's reagent is determined by a color change from clear blue to brick-red with a precipitate.
A reaction between fructose and Benedict's solution gives a positive test from the color change which occurs when the fructose is reduced to simple sugar such as glucose and mannose.
Thus, the student will use Benedict's test to support her argument.

u change t to seconds
plz hep me tell ans of this only
We have no idea what force the object might exert until it hits something.
In order to accelerate 70 kg at the rate of 20 m/s^2, YOU or some machine has to PUSH it with a force of (F=m•a) 1,400 Newtons. If you stop pushing it, it stops accelerating.

State which type of variable is plotted on the x-axis
and which type is plotted on the y-axis.
Answer:
Often the independent variable is plotted on the x-axis - and example might be time (an experiment where time is measured by a watch or an independent mechanical device)
The dependent variable is often plotted on the y-axis - and example here might be the velocity or the acceleration,
It may be the responsibility of the experimenter to determine the value of the dependent variable by some type of measurement
maize is called monocot why?

explain why the rest of the group has metallic behavior but boron does not
Answer:
Since boron only has two electron shells, it is about as capable of gaining electrons as it is of losing electrons, so it behaves as a metalloid
Explanation:
Since boron only has two electron shells, it is about as capable of gaining electrons as it is of losing electrons, so it behaves as a metalloid. The other elements in this group have more electron shells, so it is much easier for them to lose their valence electrons and they behave like metals

Metallic bonds are responsible for many properties of metals, such as conductivity. Why is this possible?(1 point)
Metals have low electronegativity, so they are conductive because they pass charges easily.
Metals have low electronegativity, so they are conductive because they pass charges easily.
Two metals bonded together are going to be more conductive than a metal bonded with a nonmetal.
Two metals bonded together are going to be more conductive than a metal bonded with a nonmetal.
An attraction between a positive charge and a negative charge is created.
An attraction between a positive charge and a negative charge is created.
The bonds can shift because valence electrons are held loosely and move freely.
Conductivity is possible in metals because metallic bonds can shift due to the fact that valence electrons are held loosely and move freely.
WHAT ARE METALLIC BONDS:
Metallic bonds are bonds that holds metals together. In metallic bonding, electrons are shared between positive metal ions. The electrons that flow in metals are delocalized, hence, are able to move freely. These free moving electrons are responsible for the high conductivity that metals exhibit.Therefore, conductivity is possible in metals because metallic bonds can shift due to the fact that valence electrons are held loosely and move freely.

not?
Answer:
No,ice will not float

in the accompanying,circuit a battery with an emf of 24 v is connected in series to resistor x and two identical light bulbs connected in parallel.each light bulb is Marked 6 V and 3 w .will the ammeter reading increase or decrease if another identical light bulb is connected in parallel to the existing two and another resistor is connected in series with x? explain your answers
Answer:
Explanation:
When you put another light bulb in parallel with the other two, you are not going to get something for nothing. The current drain on the battery has to go up.
Let the lightbulbs have a a resistance of r. Two light bulbs with make the resistance go to 1/2 r. The lower the resistance, the more the current. When you put the third light bulb in, the resistance will go to 1/3 r. So the current goes up.
If you put another resistor in series with x, the resistance adds. The total series resistance is 2x. The current reading will go down. The higher the resistance the lower the current.
Give reason for the following:
a) An inflated balloon was pressed against a wall after it has been rubbed with a
piece of synthetic cloth. It was found that the balloon sticks to the wall.
b) When an object is thrown up, it comes back to ground.
c) Mountaineers suffer nose bleeding at higher altitudes.
d) Foundations of high rise buildings are kept wide.
e) Deep sea divers or high altitude fliers wear special suits.
f) Walls of a dam are thickened near the base.
a) An inflated balloon was pressed against a wall after it has been rubbed with a piece of synthetic cloth. It was found that the balloon sticks to the wall. This is because a positive and negative electric charge is produced, therefore the balloon sticks to the wall.
b) When an object is thrown up, it comes back to ground because of gravitational attraction force of earth.
c) Mountaineers suffer nose bleeding at higher altitudes because the oxygen level decreases with increase in altitude, which the body cannot adjust.
d) Foundations of high rise buildings are kept wide because more is the area of contact, less is the pressure efforts. So, foundations are wide so as to decrease the possibility of the building from falling down.
e) Deep sea divers or high altitude fliers wear special suits so as prevent their body from being crushed by the water pressure. Since water pressure is maximum at deep seas and oceans, therefore, more is the risk of being injured.
f) Walls of a dam are thickened near the base so that the dam can handle the kinetic energy pressure and prevent itself from breaking down, which if not, can lead to flooding.

Explain a lever and a pivot in a full sentence
Answer:
The lever is a movable bar that pivots on a fulcrum attached to a fixed point. The lever operates by applying forces at different distances from the fulcrum, or a pivot. As the lever rotates around the fulcrum, points farther from this pivot move faster than points closer to the pivot.

Who has the greater velocity, an astronaut who has just completed an orbit of the Earth or you when you have just traveled from home to school? Explain.
Answer:
the answer is
Explanation:
constant acceleration
because when the object's velocity is changing then the object is accelerating or decelerating
as acceleration describe changing of velocity so the answer is constant acceleration
Acceleration is defined as the rate of change of velocity.
Acceleration = (Change in velocity) / time taken
Acceleration = (Final velocity - initial velocity) / time
As the object velocity changes by the same amount in each second, it means the acceleration is constant.
