The speed of Nancy who ran a distance of 5 km in 30 minutes is 10000 meters(m) per hour(h).

<h3>What is the rate of speed?</h3>

The rate of speed is the rate at which the total distance is travelled in the time taken. Rate of speed can be given as,

s=\dfrac{d}{t}

Here, (d) is the distance travelled by the object and (t) is the time taken but the object to cover that distance.

Nancy ran a distance of 5 km in 30 minutes. There are 60 minutes in one hour. Thus, the time in hour for which Nancy ran is,

t=\dfrac{30}{60}\\t=0.5\rm\; hr

The meters in 5 kilometers is,

d=5\times1000\\d=5000\rm\; m

She ran 5000 kilometers in 0.5 hours. Thus, the speed of her is,

s=\dfrac{5000}{0.5}\\s=10000\rm\; km/hr

Thus, the speed of Nancy who ran a distance of 5 km in 30 minutes is 10000 meters(m) per hour(h).

antiseptic1488 [7]

Answer:

A. Sound waves can travel through and reflect off rock layers.

Explanation:

Reflection seismology is a process of "seeing" below the ground using artificial sources to create sound waves or the process of learning about rock layers beneath the surface of Earth using sound waves.

Sources on land, uses vibration trucks to shake the ground very powerfully to produce sound waves.

Thus, the sound waves will travel through the earth and reflect off rock layers having different acoustic properties. In order to record this reflections, we make use of a small instrument called geophones.

What is the basic definition of a black hole?
polet [3.4K]

Explanation:

Black holes are the most massive and dense objects in the whole universe. They are peculiar objects. The gravity near black hole is so strong that even light can not escape it. That is why the name: Black hole. It is formed after the death of a supermassive star. All the mass of the star is condensed in to a very small area having a very string gravity. Imagine the Sun squeezed in to an object of diameter of just 3 km!

You can define it as a dead super massive star from which nothing can escape.

PLEASE SOLVE FAST!!! If the average American watches hours of TV every day , how many minutes will be spent in front of the TV b
masha68 [24]

Answer:

5694000 min

Explanation:

Let's suppose the average American watches 4 hours of TV every day. First, we will calculate how many minutes they watch per day. We will use the conversion factor 1 h = 60 min.

(4 h/day) × (60 min/1 h) = 240 min/day

They watch 240 minutes of TV per day. Now, let's calculate how many minutes they watch per year. We will use the conversion factor 1 year = 365 day.

240 min/day × (365 day/year) = 87600 min/year

They watch 87600 min/year. Finally, let's calculate how many minutes they spend watching TV in 65 years.

87600 min/year × 65 year = 5694000 min

The magnitude of the voltage induced in a conductor moving through a stationary magnetic field depends on the _______ and the __
Virty [35]

The correct answer is: Option (D) length, speed

Explanation:

According to Faraday's Law of Induction:

ξ = Blv

Where,

ξ = Emf Induced

B = Magnetic Induction

l = Length of the conductor

v = Speed of the conductor.

As you can see that ξ (Emf/voltage induction) is directly proportional to the length and the speed of the conductor. Therefore, the correct answer will be Option (D) Length, Speed
