Answer:

Because of the speed of the sound.

Explanation:

The first thing that happens in such cases is to take into account the speed of the sound. First, we see that the player hits the ball with the bat, if we are in the stands far enough we will hear the sound of the batting time later, this time depends on the speed of the sound which is equal to 345 [m/s].

Another visible and practical example is a fireworks display, where people nearby immediately hear the explosion. while those at a great distance will be able to see first the explosion followed by the sound.

With the following equation, we can calculate how long it takes to hear a hit or explosion

t = x / v

where:

x = distance [m]

v = sound velocity = 345 [m/s]

t = time [s]

A can of tuna, starting from rest, is dropped off a building. If it is only being pulled down by gravity (-9.8 m/s2) and it hits
tia_tia [17]

Answer:

<h3>50.23m</h3>

Explanation:

The distance talks about how far an object has travelled.

Given

9 = -9.8m/s²

t = 3.2s

to get the distance Δx, we will use the formula;

S = ut+1/2gt²

S = 0(3.2)+1/2(-9.8)(3.2)²

S = 0-4.905(10.24)

S = -50.23m

Hence the can of tuna drop by 50.23m

If a 15kg mass weighs 372 N on Jupiter, what is Jupiter's gravitational acceleration?
Dimas [21]

Answer:

Jupiter's gravitational acceleration is 24.8 m/s^2

Explanation:

Recall that the weight under the influence of a gravitational acceleration G is defined as:

Weight = m * G

Then, in our case we have

372 N = 15 kg * G

G = 372/15  m/s^2

G = 24.8 m/s^2

Make a list of nutrients found in packed items and amount of nutrient present in them
mezya [45]

Nutrients found in packed items include carbohydrates, fats and proteins and the amount of nutrients present in them is found in calories/grams.

<h3>What are macronutrients?</h3>

Macronutrients are nutrients that contain calories that must be consumed in the diet to perform metabolic functions.

These macronutrients are specified in packed foods, and include proteins, carbohydrates and lipids.

Macronutrients provide 4 calories (proteins and carbohydrates) or 9 calories per gram (fats).

In conclusion, nutrients include carbohydrates, fats (lipids) and proteins and their proportions are expressed in grams.

The cart is initially at rest. Force
Oliga [24]

Answer:

v'=\dfrac{1}{2}v

Explanation:

Given that,

Initial speed of the cart, u = 0

Let F force is applied to the cart for time \Delta t after which the car has speed v. The force on an object is given by :

F = ma

m is the mass of the cart

We need to find the speed of second cart, if the same force is applied for the same time to a second cart with twice the mass. Force becomes,

F=\dfrac{mv'}{t}

v'=\dfrac{F t}{2m}

v'=\dfrac{1}{2}v

So, the speed of second cart is half of the initial speed of first cart. So, the correct option is (b).
