HELLPPPP. The metalloid that has three valence electrons is __________

saul85 [17]

Answer:

"Non-uniform velocity" occurs when an object changes its velocity upon motion. This happens when the object either accelerates or decelerates (negative acceleration) in its speed or changes its direction.

Explanation:

"Velocity" refers to speed with a specific direction.

If the velocity is uniform, there's no change in speed and direction. However, if changes occur on either the speed, direction or both, then the velocity becomes variable or non-uniform.

For example, when it comes to a moving car, it is said to be in non-uniform velocity if the distances covered is unequal in relation to the equal intervals of time.

A student walks 4 block east, 7 blocks west, 1 blocks east then 2 blocks west in an hour. Her average speed is____ block/hour

Gemiola [76]

Average speed = (total distance) / (total time)

Average speed = (4+7+1+2 blox) / (1 hour)

Average speed = 14 blocks/hour

I'm gonna go out on a limb here and take a wild guess:

I'm guessing that there's another question glued onto the end of this one, and it asks you to find either her displacement or her average velocity. I'm so sure of this that I'm gonna give you the solution for that too. If there's no more question, then you won't need this, and you can just discard it. I won't mind.

Average velocity = (displacement) / (time for the displacement)

"Displacement" = distance and direction from the start point to the end point, regardless of how she got there.

Displacement = (4E + 7W + 1E + 2W)

Displacement = (5E + 9W)

Displacement = 4 blocks west

Average velocity = (4 blocks west) / (1 hour)

Average velocity = 4 blocks/hour West

A speeding car traveling at 24.8 m/s passes a police car that is at rest. The police car begins its pursuit at the instant the s

marusya05 [52]

Answer:

the acceleration required is 1.37m/s^2

Explanation:

The car is having a constant velocity movement, so if we calculate the time to reach 897m, we can use it to find the acceleration the policeman need to apply to reach the car.

$x=v*t\\t=\frac{x}{v}\\t=\frac{897m}{24.8m/s}\\t=36.17s$

the policeman is traveling with a constant acceleration starting from rest so:

$x=\frac{1}{2}*a*t^2\\\\a=\frac{2*x}{t^2}\\\\a=1.37 m/s2$

Air resistance allow objects to develop full acceleration due to gravity true or false

Aloiza [94]

False. because the object cannot freefall due to resistance, so it cannot develop full acceleration.
