The gravity in the space shuttle is approximately equal to the gravity on the surface of the earth
The complementary base pair is:
TTC, CTG, AGT, CTA.
Answer:
The top of the ladder go down by 0.15 m.
Explanation:
Here we have right angled triangle.
Hypotenuse = 4.6 m
Bottom angle = 66º
Length from ladder bottom to wall bottom = 4.6 cos66 = 1.87 m
Length from ladder top to wall bottom = 4.6 sin66 = 4.20 m
New length from ladder bottom to wall bottom = 1.87 + 0.31 = 2.18 m
By Pythagoras theorem
New length from ladder top to wall bottom is given by
Distance the top of the ladder go down = 4.20 - 4.05 = 0.15 m
Answer with Explanation:
We are given that
Dipole moment=C-m
Because
Magnitude of electric field,E= N/C
a.We have to find the magnitude of torque on the dipole when
dipole is parallel to the electric field
i.e
We know that
Substitute the values then we get
Because sin 0=0
b.
By using
Nm
c.
Nm
By using
d.Potential energy, U=
Because cos 0degree=1
The electric force between two charges is:
F = (9 x 10⁹) Q₁ Q₂ / D²
F is the force, in Newtons
Q₁ and Q₂ are the two charges, in Coulombs
D is the distance between them, in meters
I'm going to assume that the first little 'c' in the question stands for "Coulombs", and the second little 'c' stands for "centimeters". And now, I'll proceed to answer the question that I've just invented.
For these two electrons:
F = (9 x 10⁹) (1.6 x 10⁻¹⁹) (1.6 x 10⁻¹⁹) / (5.4 x 10⁻⁷)²
F = (9 x 1.6 x 1.6 x 10⁻²⁹) / (5.4² x 10⁻¹⁴)
F = (23.04 / 29.16) x 10⁻¹⁵
<em>F = 7.9 x 10⁻¹⁶ of a Newton</em>
<em></em>
EACH electron feels that same force, pushing it away from the other electron.
