The rate at which the location of an object shifts in any direction. Speed is measured as the ratio of the distance travelled to the time it took to cover that distance. Speed is a scalar quantity since it just has a direction and no magnitude.
<h3>Explain about the speed?</h3>
It speaks of the motion of an object. Speed is calculated as distance travelled divided by time. Speed is measured in m/sec. Speed is a scalar quantity equal to the magnitude of the velocity vector. When a thing's speed is higher, it moves more quickly.
Speed refers to the rate at which a distance varies over time. It has a time-distance dimension. As a result, the SI unit of speed is created by combining the basic units of time and distance. As a result, the SI unit of speed is the meter per second (m/s)
The formula for an object's general speed is [Speed = Distance Time]. M/s is the SI unit of speed.

Hello there!
For this:
1). Convert 10km to meters!
2). Convert the 30 minutes into seconds!
3). Use the following formula to solve for speed!
speed= distance/time
Note: The units should automatically work out to m/s. :)
My goal is to make sure you understand the problem, which is why I won't be giving you the answer. It'll be more work now, but less work in the future! :)
Hope this helped!

Answer:
K
Explanation:
The Heisenberg uncertainty principle is
Δx Δp ≥ h' / 2
h’ =
The kinetic energy of a particle is
K = ½ m v²
p = mv
v =
substitute
K =
from the uncertainty principle,
Δp =
we substitute
K =
Hello!
Using Hooke's law, F spring=k delta x, find the distance a spring with an elastic constant of 4 N/cm will stretch if a 2 newton force is applied to it.
Data:
Hooke represented mathematically his theory with the equation:
F = K * Δx
On what:
F (elastic force) = 2 N
K (elastic constant) = 4 N/cm
Δx (deformation or elongation of the elastic medium or distance from a spring) = ?
Solving:
simplify by 2
Answer:
B.) 1/2 cm
