Answer:
Explanation:
F = ma. For us, this looks like
60 = 30a and
a = 2 m/s/s
If the force goes up to, say, 90, then
90 = 30a and
a = 3...if the force goes up, the acceleration also goes up.
If the mass goes up to say, 60, and the force stays the same, then
60 = 60a and
a = 1...if the mass goes up, the acceleration goes down.
Answer:

It will float.
Explanation:
Hello.
In this case, given the width, length and height, we can compute the volume as follows:

Moreover, since the density is computed via the division of the mass by the volume:

We obtain:

In such a way, since the solid has a lower density than the water, we infer it will float.
Best regards.
Answer:
Explanation:
The relation between activity and number of radioactive atom in the sample is as follows
dN / dt = λ N where λ is disintegration constant and N is number of radioactive atoms
For the beginning period
dN₀ / dt = λ N₀
58.2 = λ N₀
similarly
41 = λ N
dividing
58.2 / 41 = N₀ / N
N = N₀ x .70446
formula of radioactive decay


- λ t = ln .70446 = - .35
t = .35 / λ
λ = .693 / half life
= .693 / 5715
= .00012126
t = .35 / .00012126
= 2886.36
= 2900 years ( rounding it in two significant figures )
The elements fluorine and chlorine can form minerals in the "halide"group
.
Halide refers to the group containing halogens. The halogens turn out to be less responsive as you go down the group. Fluorine, at the highest point of the group, is the most responsive or reactive halogen. It is to a great degree risky, causing serious synthetic consumes on contact with skin.
Halogens also act as bleaching agents.They will evacuate the shade of colors. Chlorine is utilized to bleach wood mash to influence white paper.
Answer:
Sutures are nonmoving joints that connect bones of the skull
Explanation:
These joints have serrated edges that lock together with fibers of connective tissue.
