Distance is the total length of the follwed by a movig partical.
Velocity is the rate of change of distance with respect to time. acceleration is the rate of change of velocity with respect to time.

Distance is measurable velocity is the speed of something and acceleration is the capacity to gain speed within a short amout of time
EXAMPLES
distance how far utah is from california
velocity the time it take you to run home
acceleration is like how soon a car reaches 25 mph

How can you find directions using satellite orbiting?

quester [9]

Answer:

Satellites may move north to south, or south to north, or west to east, but never from east to west. When satellites are launched, they always head eastward to take advantage of the Earth's rotation, going more than 1,000 miles per hour near the equator. This saves a lot of fuel.

One ounce of a well-known breakfast cereal contains 104 Calories (1 food Calorie = 4186 J). If 2.5% of this energy could be conv

GalinKa [24]

Answer:

482.4 kg

Explanation:

104 calorie = 435344 J

The 2.5% of this energy equals to

435344 * 0.0025 = 10883.6 J

If this energy is converted to work done on lifting a barbell by a distance of 2.3. By the formula of Work W = force * distance then the force he exerts on the barbell is

$F = \frac{W}{D} = \frac{10883.6
}{2.3} = 4732 N$

Assuming gravitational constant g = 9.81 m/s2 then the mass of the barbell is

m = 4732 / 9.81 = 482.4 kg

I have four questions.

Inga [223]

Answer:

The potential energy of the ball is 784 joules. And the kinetic energy of it is 392 while falling halfway down.

Explanation:

PE = mass (2kg) * Gravitational acceleration (9.8 m/s^2)* height (40 meters)

KE = 1/2 mass (1 kg) * velocity^2 (19.8)

Currents may also be generated by density differences in water masses caused by temperature and salinity variations. These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.Feb 14, 2013

A rock tied to the end of a string moves in a circle at a constant speed of 2.5 m/s and experiences an acceleration of 4.0 m/s.

artcher [175]

The radius of the circular motion at the given speed is 1.56 m.

The given parameters;

speed of the rock, v = 2.5 m/s
acceleration of the rock, a = 4 m/s²

The radius of the circular motion is calculated by using centripetal acceleration formula as follows;

$a_c = \frac{v^2}{r} \\\\r = \frac{v^2}{a_c} \\\\r = \frac{2.5^2}{4} \\\\r = 1.56 \ m$

Thus, the radius of the circular motion at the given speed is 1.56 m.
