Answer:
Presidents use the same criteria: legal expertise, party affiliation, philosophy, an da sense of the acceptability to the Senate. Define majority opinion, concurring opinion, and dissenting opinion.
Explanation:
The weight of an object at the surface of a planet is given by:
where m is the mass and g is the gravitational acceleration, given by
where G is the gravitational constant, M is the planet's mass, and r the radius of the planet.
At Earth's surface,
. Since we know the weight of the person at Earth's surface, F=670 N, we can find his mass:
Now we have to calculate the value of g at the surface of the neutron star. The mass of the neutron star is 25 times the Sun's mass:
While its radius is:
Therefore, the value of g at the neutron star surface is
Therefore, the weight of the person at the surface of the neutron star would be
The answer would be:
Move from one atom to another; the atom that looses an electron becomes positively charged and the atom that gains an electron becomes negatively charged.
It is the movement of electrons from on atom to another that enables elements to form chemical bonds. If electrons do not move, they are shared. The atom that loses an electron becomes positive because it would have less electrons than protons. The atom that accepts the electron becomes negative because it would have more electrons than protons.
Just remember that all elements are neutral, or they have the same number of protons and electrons. They become charged when they lose or gain one.
Answer:
a. 1.75 Nm²/C
b. Yes.
Explanation:
a. Electric Flux is given as:
Φ = E*A*cosθ
Where E = electric flux
A = Surface area
Φ = 14 * 0.25 * cos60
Φ = 1.75 Nm²/C
b. Yes, the shape of the sheet will affect the Flux through it. This is because flux is dependent on area of the surface and the area is dependent on the shape of the surface.
Answer:
Explanation:
we know that
s=vt here v is the speed and s is distance covered by the signals
given data
v=3*10^8
t=10 min we have to convert it into seconds
1 minute=60 seconds
so
10 minutes =10*60/1 =600 seconds
now putting the value of v and t we can find the value of s
s=vt
s=3*10^8*600
s=1.8*10^11m
i hope this will help you
