For each of the following velocity vectors, give the vector component, the scalar component, and the magnitude. (a) v = 48.0j m/
Oduvanchick [21]

Obtaining the component part of the letter 'i' warns that it is the velocity is oriented on the X axis. At the same time the numeric part, in this particular case will represent the scalar part and therefore the magnitude of the vector.

The velocity is

\vec{v} = 48.0\hat{i} \text{ m/s }

The vector component of the velocity is

v_x = 48.0m/s

The scalar component of the velocity is

v = 48.0m/s

The magnitude of the velocity is

v = 48.0m/s

A particle of mass 6.3 x 10-8kg and charge 7.1 muC is traveling due east. It enters perpendicularly a magnetic field whose magni
ASHA 777 [7]

Answer:

t=0.016s

Explanation:

we can use

\frac{v}{r}=\omega=\frac{qB}{m}=\frac{7.1*10^{-6}C*1.7T}{6.3*10^{-8}kg}=191.58s^{-1}

the time that the particle is in the magnetic field is one half oa period. Hence

t=\frac{T}{2}=\frac{\pi}{\omega}=0.016s

I hope this is useful for you

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.
