D = vt
where:
v = speed
d = distance
t = time
Based on the formula, each quantity is directionally proportional to each other. Since we don't have enough numbers to work with, we will utilize our concept skills.
If the car travels half the speed, then the car is slowing down and covers a short distance in a certain amount of time than it did originally. So we divide the default distance by 2.
180 / 2 = 90
The new distance so far is 90 miles.
But now it takes the car 3 times as long to get to its destination. The longer it takes, the more distance you will cover. Multiply the current distance by 3.
90 * 3 = 270
Answer:
Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work? We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).
Explanation:
Answer:
434.0 V/m
Explanation:
The power output of the laser is:
while the radius of the beam is
so the cross-sectional area is
So the intensity of the laser beam is
The intensity of a laser beam is related to the magnitude of the electric field by
where
c is the speed of light
is the vacuum permittivity
Solving the formula for E, we find
let the moles of chlorine-35 is n1 and chlorine-37 is n2
now we will use the formula of average atomic mass
here let say
so here since ratio of moles of chlorine 35 and chlorine 37 is more than 1 so chlorine 35 is more in the proportion in this mixture so <em>there is most chlorine atom consist of 18 neutrons</em>
Global warming is what will happen
