How is newton’s first law of motion used for a person in a stationary car during a car crash

Physics
1 answer:
babunello [35]2 years ago

Answer:

When the car crashes, there is no unbalanced force acting on the person, so they continue forward (Newton's First Law). The person moves against the seat belt, exerting a force on it.

A relief airplane is delivering a food package to a group of people stranded on a very small island. The island is too small for
strojnjashka [21]

speed of the plane is given as

v = 442 km/h = 122.8 m/s

height of the plane is

h = 575 m

acceleration due to gravity is

g = 9.80 m/s^2

part a)

when package is dropped its vertical speed is zero so we can use kinematics to find the time of drop

\delta y = v_y * t + \frac{1}{2}gt^2

575 = 0 + \frac{1}{2}*9.80*t^2

t = 10.83 s

Part b)

Horizontal distance moved by the package is given by

\delta x = v_x * t

\delta x = 122.8 * 10.83

\delta x = 1330.3 m

Part c)

final speed in x direction

v_x = 122.8 m/s

final speed in y direction

v_y = 9.8*10.83 = 106.13 m/s

so net speed as it hit the ground will be

v = \sqrt{v_y^2 + v_x^2}

v = \sqrt{122.8^2 + 106.13^2}

v = 162.3 m/s

(WILL MARK BRAINLIEST and 25pts) Another term for angular distance is
vagabundo [1.1K]

Answer:

C. Angular Separation

Explanation:

The term angular distance (or separation) is technically synonymous with angle itself, but is meant to suggest the (often vast, unknown, or irrelevant) linear distance between these objects (for instance, stars as observed from Earth).

Validity of an experiment is based upon
igor_vitrenko [27]

Validity concludes the whole experimental values and concepts which makes that whether the results which are obtained meet all of the requirements of the scientific research method.

On which factors the validity of an experiment depends?

There are five components which are used in experiment: observations, questions, hypothesis, methods and results. The scientific method procedure is not only ensures that the same experiment can be repeated by other researchers, but this experiment is accepted. For example, there must have been arrange in a random way of the sample groups and proper work and care shows and the experiment is succeed.

So we can conclude that: Validity concludes the whole experimental values and concepts which makes that whether the results which are obtained meet all of the requirements of the scientific research method.

Can one individual represent and entire population? Why or why not
zubka84 [21]

Answer:

Explanation:

A representative does his/her utmost to convey the feelings of the majority of the group they speak for, and stands up for their interests. This might be for negotiation, voting, litigation, diplomacy, etc.  

A leader, ideally, inspires their constituents and brings out the best in them, as in strength, ethics, spirituality, and so on.  

Short version: a rep is an agent or conduit. A leader is a catalyst. Either job can be hard. And yes, it can be done for most of a population. Maybe not all, but not everyone can fit into the same mold.
