1. What is the average speed of a car that travels a distance of 120 miles in 2 hours?Solution:Distance = 120 milesTime = 2 hoursUse the speed formula to calculate the speed.Speed $= \frac{Distance}{Time}$Speed $= \frac{120 \;miles}{2 \;hours} = 60$mph...
In the studies of science and mathematics, the quantities of distance, rate, and time are closely related by a well-known rule. We can use this rule to derive formulas for each of these quantities in terms of the other two quantities....

A floating ball normally weighs 7 N.The acceleration of gravity is 9.8 m/s^2. What is the size of the buoyant force that acts on it? (Answer in units of N.) Show how to calculate mass using density and volume. What is formula for surface charge density? The mass of an object is ...
(a) In order to calculate the speed in centimetres per second we should convert the given distance of 3 kilometres into centimetres and the given time of 5 minutes into seconds. Please note that 1 kilometre has 1000 metres and 1 metre has 100 centimetres. Now, Distance travelled = 3 km ...
formula to calculate drift velocity relation between drift velocity and electric current relation between drift velocity and current density frequently asked questions – faqs what is drift velocity? subatomic particles like electrons move in random directions all the time. when electrons are subjected ...
This value is different for different massive bodies that create this kind of acceleration. What is the formula for gravity? The force of gravity measures the intensity of the attraction between two massive bodies. It can be calculate as F = (G * m1 * m2) / d^2. Where G is the ...
For example, if a car has a speed of 20 m/s and is moving around a circular track with a radius of 5 m, we can calculate its centripetal acceleration: [ text{Centripetal Acceleration} = frac{v^2}{r} = frac{(20)^2}{5} = 80 , text{m/s}^2 ] ...
To calculate linear velocity, first determine if the object in question is moving at a constant speed and/or a constant acceleration. If the object has a constant speed, the linear velocity, v, is the change in position over the change in time (v = Δs/Δt]. If the object has a co...
Why there is a standard unit for measuring the length, distance, speed, time? The speed limit on some interstate highways is roughly 120 km/h. What is this in meters per second? What is the SI unit of acceleration? How do I find the average speed of an object that traveled 3 miles ...
