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.

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.

No,ice will not float

Explanation:

A substance sinks in another if it has a greater density than the other substance. The density of ice is clearly greater here and so ice will sink

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

Answer:

Explanation: 100 watts is a unit of power.

A watt is also the amount of energy being consumed. So the more watts the brighter the light bulb is lit.

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.

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.

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

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.

Answer:

The difference in the concentration of a substance between two areas is called the concentration gradient . The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse. The direction of diffusion is said to be 'down' or 'with' the concentration gradient.

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.
