How is ur finger related to the parallax stars

Use the drop-down menus to complete each statement.

Ivanshal [37]

Answer:

The amount of matter in an object is its mass

An action that has the ability to change an object's state of motion is a force

The rate at which velocity changes over time is acceleration

Explanation:

- Mass is a scalar quantity that gives a measure of the amount of matter contained in an object/substance. The SI unit of the mass is the kilogram (kg). Mass is an intrinsec property of an object, that means that it does not change when the object is moved in another location.

- A force is a vector quantity, that indicates an action exerted on an object that changes the state of motion of the object. It is measured in Newtons (N). According to Newton's second law, the acceleration of an object is equal to the net force exerted on the object divided by its mass:

$a=\frac{F}{m}$

- Acceleration is a vector quantity, which is equal to the ratio between the change in velocity of an object and the time interval taken for that change to occur. It is measured in meters per second squared ( $m/s^2$ ). Mathematically, it is defined as

$a=\frac{\Delta v}{\Delta t}$

A boy throws a snowball straight up in the air with an initial speed of 4.50 ft/s from a position 4.00 ft above the ground. The

IgorC [24]

Answer:

a) 0.658 seconds

b) 0.96 inches

Explanation:

$v=u+at\\\Rightarrow 0=4.5-32.1\times t\\\Rightarrow \frac{-4.5}{-32.1}=t\\\Rightarrow t=0.14 \s$

Time taken by the ball to reach the highest point is 0.14 seconds

$s=ut+\frac{1}{2}at^2\\\Rightarrow s=4.5\times 0.14+\frac{1}{2}\times -32.1\times 0.14^2\\\Rightarrow s=0.315\ ft$

The highest point reached by the snowball above its release point is 0.315 ft

Total height the snowball will fall is 4+0.315 = 4.315 ft

$s=ut+\frac{1}{2}at^2\\\Rightarrow 4.315=0t+\frac{1}{2}\times 32.1\times t^2\\\Rightarrow t=\sqrt{\frac{4.315\times 2}{32.1}}\\\Rightarrow t=0.518\ s$

The snowball will reach the bank at 0.14+0.518 = 0.658 seconds after it has been thrown

$v=u+at\\\Rightarrow v=0+32.1\times 0.518\\\Rightarrow v=16.62\ ft/s$

$v^2-u^2=2as\\\Rightarrow s=\frac{v^2-u^2}{2a}\\\Rightarrow s=\frac{0^2-16.62^2}{2\times -100\times 3.28}\\\Rightarrow s=0.42\ ft$

The snowball goes 0.5-0.42 = 0.08 ft = 0.96 inches

Who pioneered the use of galvanoplastic compounds for preserving footprints and ballistics?

alukav5142 [94]

Answer:

Option D (Alphonse Bertillon) is the correct response.

Explanation:

He seems to have been a policeman turned biometrics expert from France. Forensic techniques such as forensic record analysis were developed by Bertillon.
To retain proof, he always pioneered or developed the use of such galvanoplastic compounds as molds for footsteps as well as ballistics. To research physical changes with age, Bertillon has developed a method focused on images of almost the same person’s performance.

All those other choices weren’t connected to the instance offered. So, the best one is the one described.
