Answer:
\frac{R}{^{\sqrt{2}}}
Explanation:
q1 = q , q2 = q
m1 = M, m2 = 2M
Potential difference is V
Let v1 be the speed of first particle and v2 be the speed of second particle.
Energy due to potential difference gives the kinetic energy to the particle.
1/2 m x v^2 = e V
v^2 = 2 e V / m = 2e V / m ... (1)
Now radius is given by
r = m v / B q
by eqution (1)
For first particle
.... (2)
For second particle
.... (3)
Divide equation (2) by equation (3), we get
So
r1 / r2 =
Answer
there are strong attractive forces between atoms of liquids with a high viscosity
Explanation:
viscosity:
Viscosity is the state of being sticky and thick . There are strong attractive forces between atoms of liquids with a high viscosity on the other hand in non viscous liquid there are weak attractive forces between atoms of liquids. A semi fluid liquid like jelly is said to be viscous. Viscosity increases with stronger inter molecular forces at normal temperature. Viscosity decreases as temperature increases

Answer:
There's no risk of animals or bad weather interfering with your campsite, either. You don't even really need a tent. A sleeping pad, sleeping bag and a mindful eye to pick up everything you brought in is all you really need to enjoy overnight caving. Do your research
Explanation:
Scientists can directly observe the rate of nuclear decay for all radioactive elements.
Scientists can calculate the half-life of all radioactive elements using the rate of nuclear decay
Explanation:
The true statements from the given options is that "scientists can directly observe the rate of nuclear decay for all radioactive elements" and "scientists can calculate the half-life of all radioactive elements using the rate of nuclear decay".
Let us carefully examine the original statement:
Scientists can directly observe the half-life of all radioactive elements
The keywords from here are:
directly observe
half-life
radioactive elements
to directly observe implies that evaluative information about the half-life is being gathered. In making observations, calculations can be made to make deductions.
half-life is the time taken for half of radioactive nuclei to disintegrate.
Radioactive elements are unstable nuclei that will naturally decay on their own into other nuclei.
It is correct to say that scientist can directly observe the rate of nuclear decay for all radioactive element. The half-life is one of the ways of measuring the rate of decay.
Scientists can calculate the half-life of all radioactive elements using the rate of nuclear decay also.
