how far south of his starting point will he be when he reaches the opposite bank? hint: for constant velocity problems, a distance is merely the velocity in the direction of the distance traveled, multiplied by the travel time.

Answers

Answer 1

The traveler will be 50 miles south of his starting point when he reaches the opposite bank.

What is velocity?

Velocity is a measure of the rate at which an object moves through space and time. It is expressed in terms of the speed and direction of an object's movement and is typically measured in meters per second (m/s). Velocity can also be used to describe the rate at which a function or process changes over time, such as the velocity of a company's growth or the velocity of a stock price change.

To answer this question, we need to know the starting point, the opposite bank, the velocity of the traveler, and the time it will take to travel from the starting point to the opposite bank. Assuming the traveler is moving at a constant velocity, the distance he will travel will be the velocity multiplied by the travel time.

For example, if the starting point is 0 miles from the opposite bank, and the traveler is moving at a velocity of 50 miles per hour, and it takes him 1 hour to get to the opposite bank, then the distance he will travel is 50 miles. Therefore, the traveler will be 50 miles south of his starting point when he reaches the opposite bank.

a pebble is dropped from rest from the top of a tall cliff and falls 94.9 m after 4.4 s has elapsed. how much farther does it drop in the next 8.8 s?

Answers

The pebble drops 758.9 m in the next 8.8 s. The result is obtained by using the equation in uniformly accelerated motion.

What are the equation in uniformly accelerated motion?

The equations apply in uniformly accelerated motion in vertical dimension are

v₁ = v₀ + gt

v₁² = v₀² + 2gh

h  = v₀t + ½ gt²

Where

v₀ = initial velocityv₁ = final velocityg = acceleration due to gravityt = timeh = height of object

A pebble is dropped from rest from the top of a tall cliff. It falls 94.9 m after 4.4 s and is still falling for 8.8 s. Find how much farther it drops!

See the illustration picture for a pebble dropping in the attachment!

We use g = 9.8 m/s².

The total time is 4.4 + 8.8 = 13.2 s.

The initial velocity of the pebble dropping is 0. So, v₀ = 0.

Using one of the above equations, we get the height.

h  = v₀t + ½ gt²

h  = 0 + ½ (9.8)(13.2)²

h  = ½ (9.8)(13.2)²

h = 853,8 m

The next 8.8 s, the pebble will fall

h₁ = h - 94.9

h₁ = 853.8 - 94.9

h₁ = 758.9 m

Hence, in the next 8.8 s, the pebble will drop 758.9 m.

What is the Newton's law of universal gravitation?

The Newton's law of universal gravitation states that every object with the mass in the universe attracts to each other. The pulling force is called gravitational force. The gravitational force can be expressed as

F = Gm₁m₂/r²

Where

F = gravitational forceG = gravitational constatm₁ and m₂ = mass of objectsr = distance of mass of objects

If a mass of Earth were increased by a factor of 9, find the gravitational force between the Earth and the Sun would be!

Let's say

m = mass of the EarthM = mass of the Sun

Without increasing the mass of the Earth, the gravitational force is

F = GMm/r²

The mass is increasing 9 times. So, now the mass of the Earth is 9m.

How does the movement of water molecules change when water goes from liquid to gas ?

Answers

When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle.

What is evaporation?

Evaporation is a type of vaporization that occurs at the surface of a liquid as it changes to a gas phase.A high concentration of the evaporating substance in the surrounding gas significantly slows evaporation, for example when humidity affects the evaporation rate of water.When liquid molecules collide, they transfer energy to each other as they collide. When a molecule near the surface absorbs energy to overcome the pressure, it escapes and enters the surrounding air as a gas.When evaporation occurs, the energy removed from the evaporated liquid lowers the temperature of the liquid, resulting in evaporative cooling.

Blocks A and B oscillate at the ends of identical springs. The period of B’s oscillation is twice as long as that of A’s. How many times more massive is block B than block A?

Answers

The period of oscillation is the time it takes for an object to complete one full oscillation, and it is inversely proportional to the square root of the spring constant and directly proportional to the square root of the mass of the object. The period of oscillation is given by the formula T = 2π √(m/k) where T is the period, m is the mass of the object, and k is the spring constant.

Let's assume that the period of A's oscillation is T1 and the period of B's oscillation is T2. From the problem statement, we know that T2 = 2T1. Using the formula for the period of oscillation, we can write:

T2 = 2π √(m2/k) = 2 * 2π √(m1/k) = 2T1 = 2π √(m1/k)

Dividing the equation T2 = 2T1 by T1, we get T2/T1 = 2

To calculate velocity, the displacement (change in position) is divided by the time elapsed. Both speed and velocity are fundamental concepts in physics and are used in many areas of study, including mechanics, thermodynamics, and astronomy.

What is the kinetic energy of a 10kg 10 kg object moving at 2.0m s 2.0 m s?

Answers

The kinetic energy of a 10kg object moving at 2.0m/s is 20 joule.

What is kinetic energy?

According to the definition of kinetic energy in physics, it is the amount of work that an item may accomplish while in motion. As a scalar quantity, kinetic energy can only be fully defined by its magnitude.

Mass of the object = 10 kg.

Speed of the object = 2.0 m/s.

Hence, kinetic energy of the object = 1/2 × mass × speed²

= 1/2 × 10 kg ×( 2.0 m/s)²

= 20 Joule.

So, kinetic energy of the object is 20 Joule.

Relative cooling rates of igneous intrusive o ms can be estimated by comparing rocks
answere : Crystal sizes

Answers

Relative cooling rates of igneous intrusive can be estimated by comparing rocks  Crystal sizes.

The size of the crystals within an igneous rock is a sign of the conditions that led to its formation. An igneous rock with large crystals typically indicates that the rock formed deep within the Earth because it is frequently warmer there than close to the surface. They are known as intrusive rocks and exhibit phaneritic textures, which derive from the Greek word phanerous, which means visible. Similar to this, a rock with tiny crystals likely originated at the surface or not far from it and cooled swiftly. These rocks have an aphanitic texture, which comes from the Greek words "a-" for not and "phanerous." They are referred to as extrusive rocks. Additionally, some magmas cool so quickly that no crystals form; in these cases, we refer to the magmas as having a hyaline texture (from the Greek "hyalis," which means glass).

what does the pressure at a point in a fluid depend on?
-The density of the fluid.
-The pressure at the fluid's surface.
-The depth of that point within the fluid.
-The weight of the fluid directly above that point.

Answers

The pressure at a point in a fluid depends on the density of the fluid.

The correct option is A.

What is fluid pressure?

The pressure of the fluid is the pressure the fluid exerts as a result of its height above the ground as well as its density.

A fluid's pressure is inversely correlated with its height above a certain point and its specific gravity or density there.

The fluid pressure is also called static fluid pressure or hydrostatic pressure.

There are several units of pressure such as pounds per square inch and bar, units of atmospheric pressure, etc.
