Answer:
static
Explanation:
static friction pushes in the direction you are walking.
<span>"A force is required to cause motion to deviate from a straight line.</span>
The rocket will cover
distance in 4. 5 s. Acceleration can be defined as the change in velocity.
<h3>
What is acceleration?</h3>
Acceleration can be defined as the change in speed or the direction of the object.
From kinamatic equation:
![D = v_{t} +\dfrac 12at^2](https://tex.z-dn.net/?f=D%20%3D%20v_%7Bt%7D%20%2B%5Cdfrac%2012at%5E2)
Where,
- final velocity = 445 m/s
- initial valocity = 0 m/s
- acceleration = 99. 0 m/s²
- time = 4. 50 s
Put the values in the formula,
![D = 0\times ( 4.5) + \dfrac12\times (99)(4.5)^2\\\\D = 1002 {\rm \ m}\\\\D = 1 \times 10^3\rm \ m](https://tex.z-dn.net/?f=D%20%3D%200%5Ctimes%20%20%28%204.5%29%20%2B%20%5Cdfrac12%5Ctimes%20%2899%29%284.5%29%5E2%5C%5C%5C%5CD%20%3D%201002%20%7B%5Crm%20%5C%20m%7D%5C%5C%5C%5CD%20%3D%201%20%5Ctimes%20%2010%5E3%5Crm%20%5C%20m)
Therefore, the rocket will cover
distance in 4. 5 s.

Answer:
an electromagnetic wave with a wavelength in the range 0.001–0.3 m, shorter than that of a normal radio wave but longer than those of infrared radiation. Microwaves are used in radar, in communications, and for heating in microwave ovens and in various industrial processes.
Answer: True
Explanation:
Class characteristics can be define as the features which are common to the group of objects. Like the make, model, label of the manufacturing company, design, shape and form. The individual characteristics can be define as the features which develop on the object or any other article with it's wear and use. Like tear, cuts, malformation and deposition of dust, dirt, and mud. The individual characteristic indicate towards the ownership of article or evidence to a particular person.
The class characteristics can only support the possibility of the evidence exactly alike that of the evidence found at the scene of crime. But the individual characteristics can directly link the evidence with the cause of crime. Hence, will be useful to prove that a crime has taken place in the court of law.
