The wave equation is
Wave speed = (frequency) x (wavelength)
When any two of the three variables are known, the wave equation can be used to determine <em>the third variable</em>.
Explanation:
Adaptations are any behavioral or physical characteristics of an animal that help it to survive in its environment
I’m unsure whether there is a question there but in forces the force weight which includes gravity would be pushing the diver directly down. However if there was enough thrust from the diver the motion would change but ultimately will be accelerating downwards because of unbalanced forces
Answer:
Weight=686.7N, , S.G.=0.933, F=17.5N
Explanation:
So, the first value the problem is asking us for is the weight of methanol. (This is supposing there is a mass of methanol of 70kg inside the tank). We can find this by using the formula:
W=mg
so we can substitute the data the problem provided us with to get:
which yields:
W=686.7N
Next, we need to find the density of methanol, which can be found by using the following formula:
we know the volume of methanol is 75L, so we can convert that to like this:
so we can now use the density formula to find our the methanol's density, so we get:
Next, we can us these values to find the specific gravity of methanol by using the formula:
when substituting the known values we get:
so:
S.G.=0.933
We can now find the force it takes to accelerate this tank linearly at
F=ma
F=17.5N
