What is the car’s average velocity (slope) between “O” and “A”? (y2-y1 / x2-x1) = slope
(1,24) (0,0)

Answer:

Yeah ice floats on water.

Observation

Example in those areas were ice is found like Antarctica ice is found on top of water.

Answer: The acceleration due to gravity increases the velocity of a falling object by 9.8 m/s per

second. Answer B is wrong because velocity increases. Answer C is wrong because the

distance increases every second. Ans. E is wrong because the derivative of distance with

respect to time gives the velocity, not the acceleration.

Explanation:

The horizontal displacement (x₀) of the object is 7 m.

The given parameters;

The vertical displacement equation of the object is given as;

h = vt + ¹/₂gt²

where;

v is the initial vertical velocity = 0

The time of motion is calculated as;

5 = 0  + (0.5 x 9.8)t²

5 = 4.9t²

[tex]t^2 = \frac{5}{4.9} \\\\t^2 = 1.02\\\\t = \sqrt{1.02} \\\\t = 1 \ s[/tex]

The horizontal displacement of the object is calculated as;

X₀ = uₓt

X₀ = 7 x 1

X₀ = 7 m

Thus, the horizontal displacement (x₀) of the object is 7 m.

Answer:

1) ironing a shirt 2) writing on surfaces 3) working of an eraser

Mass of the car (m) = 1000 Kg

Acceleration (a) = 0.05 m/s^2

Let the force we are applying to the car be F N.

By using the equation,

F = ma, we get

F = 1000×0.05 N = 50 N

Answer: We are applying 50 N force to the car in the direction of motion.

Answer:

it must be based on information that other scientists have also gathered

Answer:

hope its ok

Explanation:

Science is a way of learning about what is in the natural world, how the natural world works, and how the natural world got to be the way it is. It is not simply a collection of facts; rather it is a path to understanding.so it should contain a logical theory but it can also never be said as the final answer.

so A) OR D) both are correct

H² = B² × L²

H² = (9.2)² × (5.2)²

H² = 84.64 × 27.04

H² = 2288.6656

H = √ 2288.6656

H = 47.84

Answer:

Use Pythagorean theorem

19) A² + B² = C²

5.2² + 9.2² = C²

C = √111.68

C = 10.567875...

C ≈ 10.6

21) A² + B² = C²

B² = C² - A²

B² = 7.2² - 5.3²

B = √23.75

B = 4.873397...

B ≈ 4.9

Here,

Using Formula;

v = u + at

or, 7 = 0 + (6.6*t)

or, 7 = 6.6t

or 7/6.6 = t

or, t = 1.06s

Greatest mathematician and the most influential scientist of all time.

If the meter's battery is good and the meter is working OK, it should read zero ohms.

Most meters have a little adjustment wheel on the side to SET the reading to exactly zero when the probes are touched together.

Answer:

This is Newton's second law.

Newton's second law text:

(If a resultant force acts on a body, then an acceleration will give it an acceleration, the magnitude of which is directly proportional to the amount of the net force, and a direction is in the direction of the net force itself)

F=ma

net force = mass x acceleration
