Answer:

3 m/s

Explanation:

We'll begin by calculating the change in displacement of the jogger. This can be obtained as follow:

Initial displacement (d₁) = 4 m

Final displacement (d₂) = 16 m

Change in displacement (Δd) =?

Δd = d₂ – d₁

Δd = 16 – 4

Δd = 12 m

Finally, we shall determine the determine the average velocity. This can be obtained as follow:

Change in displacement (Δd) = 12 m

Time (t) = 4 s

Velocity (v) =?

v = Δd / t

v = 12 / 4

v = 3 m/s

Thus, the average velocity of the jogger is 3 m/s

The subfield of anthropology that describes, analyzes, interprets, and explains social and cultural similarities and differences

Makovka662 [10]

Answer:

cultural

Explanation:

Cultural anthropology studies the characteristics of the behavior learned in human societies, that is, science of human culture. In general, it is the science that studies the origin, development, structure, characteristics and variations of human culture in both past and present societies. Ethnography, ethnology, archeology, linguistics and physical anthropology are the disciplines on which cultural anthropology is founded.

As a diligent physics student, you carry out physics experiments at every opportunity. At this opportunity, you carry a 1.01 m l

Valentin [98]

Answer:

The strength of the magnetic field is $75.6\ \mu T$ .

Explanation:

Given that,

Length of the rod, L = 1.01 m

Speed with which the rod is moving, v = 3.47 m/s

We need to find the strength of the magnetic field that is perpendicular to both the rod and your direction of motion and that induces an EMF of 0.265 mV across the rod. When the rod is moving with some speed, an emf gets induced and it is given by :

$\epsilon=Blv$

B is magnetic field

$B=\dfrac{\epsilon}{lv}\\\\B=\dfrac{0.265\times 10^{-3}}{1.01\times 3.47}\\\\B=75.6\ \mu T$

So, the strength of the magnetic field is $75.6\ \mu T$ .

What statement BEST describes a solid?

BARSIC [14]

Solids: definite shape, definite volume
Because they are stiff and the molecules don't move around, they vibrate quickly.
Liquids: indefinite shape, definite volume
Because the shape or "fixed" area of liquids won't stay the same.
Gases: indefinite shape, indefinite volume
Because you've probably noticed, gases are set more freely, allowing molecules to move more freely than in solids and liquids.

a metal bal is held at rest H=65.0 cm above the floor. The ball is released with no initial velocity. How much time does it take

Fofino [41]

Answer:

Metal ball will take 0.364 seconds to reach floor.

Explanation:

Initial height from ground = 65 cm = 0.65 meter

We have equation of motion , $s= ut+\frac{1}{2} at^2$ , s is the displacement, u is the initial velocity, a is the acceleration and t is the time.

In this the velocity of body in vertical direction = 0 m/s, acceleration =acceleration due to gravity = 9.8 $m/s^2$ , we need to calculate time when s = 0.65 meter.

Substituting

$0.65=0*t+\frac{1}{2} *9.8*t^2\\ \\ t = 0.364 seconds$

So it will take 0.364 seconds to reach floor.
