Starting from home, you bicycle 25 km north in 2.4 h and then turn around and pedal straight home in 1.4 h . What are your (a) d

AnnZ [28]

Answer:

Part a)

$d = 25 km$

Part b)

$v_{avg} = 10.42 km/h$

Part c)

$v_{avg} = 17.86 km/h$

Part d)

Displacement for entire trip = 0

Part e)

Average velocity for entire trip will be zero

Explanation:

Part a)

Displacement after t = 2.4 hours is the straight line distance between initial and final positions

so we have

$d = 25 km$

Part b)

Average velocity is defined as

$v_{avg} = \frac{displacement}{time}$

$v_{avg} = \frac{25 km}{2.4 h}$

$v_{avg} = 10.42 km/h$

Part c)

During his return journey the displacement will be same

$displacement = 25 km$

$time = 1.4 h$

so average velocity is defined as

$v_{avg} = \frac{25 km}{1.4 h}$

$v_{avg} = 17.86 km/h$

Part d)

Displacement for entire trip = 0

as initial and final position will be same

Part e)

Average velocity for entire trip will be zero

What best describes the relationship between the frequency of an oscillation and the period of the oscillation?

ZanzabumX [31]

Explanation:

Let f is the frequency of an oscillation and T is the period of the oscillation. There exists an inverse relationship between the frequency and the time period of the oscillation. Mathematically, it is given by :

$f=\dfrac{1}{T}$

Also, $f=\dfrac{\omega}{2\pi}$

So,

$T=\dfrac{2\pi}{\omega}$

The time taken to complete one oscillation is called the period of the oscillation and the number of oscillation is called the frequency if an oscillation.

13. Which best summarizes the change in number and size of microcontinents during the Proterozoic?

Nutka1998 [239]

Answer:

Option C

The number of microcontinents decreased and the size increased

Explanation:

During the Proterozoic stage, it's expected that while the size of microcontinents increased, the reverse happens on the number to imply the number decreased. Therefore, option C is correct, the number of microcontinents decreased and the size increased

A person slaps her leg with her hand, which results in her hand coming to rest in a time interval of 2.25 ms2.25 ms from an init

Aliun [14]

Answer:

The force is 3305.6 N.

Explanation:

Final velocity, v = 0

time, t = 2.25 ms

initial velocity, u = 4.25 m/s

mass, m = 1.75 kg

Let the acceleration is a.

Use first equation of motion.

v = u + a t

0 = 4.25 + a x 0.00225

a = - 1888.9 m/s^2

The force is

F = ma

F = 1.75 x 1888.9

F = 3305.6 N
