When cells get ready to divide, they need to grow several different structures. What do all cells need in order to grow these st
rodikova [14]

Answer:

To survive, every cell must have a constant supply of vital substances such as sugar, minerals, and oxygen, and dispose of waste products, all carried back and forth by the blood cells. Without these substances, cells would die in a very short period of time.

A bicycle is traveling with a speed of 12 m/s. The cyclist hits the brakes reducing the speed to 4 m/s in a time of 4.8 seconds.
Annette [7]

So, the acceleration of the bicycle is approximately <u>-1.67 m/s²</u> or it can be said to be decelerating approximately <u>1.67 m/s²</u>.

<h3>Introduction</h3>

Hi ! Here I will help material about linear motion changes regularly, which is where you will hear a lot of the term acceleration. Acceleration occurs when an object's speed increases in a certain time interval. Acceleration can be negative which is called deceleration. The relationship between acceleration with velocity and time is manifested in the equation:

\boxed{\sf{\bold{a = \frac{v_2 - v_1}{t}}}}

With the following conditions :

  • a = acceleration (m/s²)
  • \sf{v_2} = object's final velocity (m/s)
  • \sf{v_1} = object's initial velocity (m/s)
  • t = interval of the time (s)

<h3>Problem Solving </h3>

We know that :

  • \sf{v_2} = object's final velocity = 4 m/s
  • \sf{v_1} = object's initial velocity = 12 m/s
  • t = interval of the time = 4.8 s

What was asked :

  • a = acceleration = ... m/s²

Step by step :

\sf{a = \frac{v_2 - v_1}{t}}

\sf{a = \frac{4 - 12}{4.8}}

\sf{a = \frac{-8}{4.8}}

\boxed{\sf{a \approx -1.67 \: m/s^2}}

So, the acceleration of the bicycle is about -1.67 m/s² or it can be said to be decelerating around 1.67 m/s².

How much time would it take for the sound of thunder to travel 2000 meters of sound travels at the speed of 330 meters per secon
SpyIntel [72]

Time = (distance covered) / (speed)

Time = (2,000 m) / (330 m/s)

<em>Time = 6.06 seconds</em>
