Answer:
True.
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
Simply stated, a vector quantity has both magnitude and direction.
Thus, a vector quantity is: A deer running 15 meters per second due west.
The answer is 800 J

The equation that describes the graph is y = 16.7x + 150.
<h3>What is the equation?</h3>
We have been given the graph of a certain function data set in physics. We know that the graph is the representation of data on cartesian coordinates. In this case, we are asked to find the equation of the graph in the form; y=mx+b
m = slope of the graph
b = intercept of the graph.
To obtain the slope;
m = y2 - y1/ x2 - x1
m = 400 - 200/ 16 - 4
m = 200/ 12
m = 16.7
Then we can see from the graph that the y - intercept is 150. Having these data, the equation that could describe the graph is now;
y = 16.7x + 150

Answer:
Explanation:
the speed of the tsunami will be
v = distance / time
v = s/t
v = 2300 / 5.3
v = 434 miles/hour
To convert this to m/s, we should note that, 1 mile = 1609 m, and thus
434 miles/hr = 434 * 1609/3600
434 miles/hr = 194 m/s
The frequency, f is given by the formula
f = velocity * wavelength
f = vλ
f = 194 * 470
f = 91180 Hz = 91 kHz
Period, T = 1/f
Period T = 1.096*10^-5 s or
Period T = 1.096*10^-5 / 60
Period, T = 1.828*10^-7 minute
Answer:
Work = Work out
Work in = 5 N * d where d is the distance the handle travels
Work out = 50 N * 7 m = 350 Joules
d = 50 N * 7m / 5 N = 70 m
This is the distance traveled by the force of 5 N
