What relationship exists betwen air resistance and acceleration of falling objects

Physics

They both make a thing go faster and slower but the relationship is force.

They are both forces that exist when an object is falling. Terminal velocity occurs when gravitational acceleration is equivalent to air resistance. :)

A statement made prior to an experiment, and based on little scientific evidence, is
Iteru [2.4K]
A- hypothesis
You usually write hypothesis in science it’s something that can usually be tested.

B- prediction
Made before you do an science experiment, they’re usually like what you think could happen or will happen.

C- theory
Theses aren’t used with scientific evidence, they’re usually things that people believe happened. Example: Some believe Big Foot is real. But no one will ever know because its a theory

D- is already been eliminated, not all are right.

Answer is A

Hope this helped :)

A boat is heading across a river at a velocity of 25 mph. The river is flowing downstream at 10 mph. What is the actual velocity
AnnyKZ [126]
Principle: Pythagorean theorem

Given:
Let a = boat velocity = 25 miles per hour
      b = river velocity = 10 miles per hour

Required: c = actual velocity

Solution:
     
     c^2 = a^2 + b^2
     c^2 = (25)^2 + (10)^2
     c^2 = 725
     (c^2)^0.5 = (725)^0.5
      c = 26.93 miles per hour

<em>ANSWER: Actual boat velocity is 26.93 miles per hour</em>

How do you find the amplitude of a wave?
Sergio039 [100]

Answer:

To find the amplitude, wavelength, period, and frequency of a sinusoidal wave, write down the wave function in the form y(x,t)=Asin(kx−ωt+ϕ).

The amplitude can be read straight from the equation and is equal to A.

The period of the wave can be derived from the angular frequency (T=2πω).

Em um centro de distribuição uma empilhadeira carrega uma caixa de 1000kg até o caminhão responsável pelo transporte desta carga
Yakvenalex [24]

Answer:

F = 592238.09 N

Explanation:

To find the mean force you first calculate the acceleration by using the following kinematic equation:

v^2=v_o^2+2ax\\\\v_o=0m/s\\\\v=10km/h\\\\x=8.4m\\\\

you do "a" the subject of the equation and replace the values of the other parameters:

a=\frac{v^2}{2x}=\frac{10000m/s}{2(8.4m)}=595.23\frac{m}{s^2}

next, the force, by using the second Newton law is:

F=ma=(1000kg)(595.23\frac{m}{s^2})=595238.09\ N

hence, the force is 592238.09 N

TRANSLATION:

Para encontrar a força média, primeiro calcule a aceleração usando a seguinte equação cinemática:

você faz "a" o assunto da equação e substitui os valores dos outros parâmetros:

Em seguida, a força, usando a segunda lei de Newton, é:

portanto, a força é 592238.09 N
