Answer:

Core samples are small portions of a formation taken from an existing well and used for geologic analysis. The sample is analyzed to determine porosity, permeability, fluid content, geologic age, and probable productivity of oil from the site. ... Core samples reveal the physical and chemical nature of the rock.

Consider the trajectory of a charged particle that is moving with a speed 0.8c in the x direction when it enters a large region

Valentin [98]

Answer:

Explanation:

The electric field applies a force qE, but only in the y direction. This means that the x component of the

momentum must be conserved:

0 = Fx =dpx/dt

=⇒ px is conserved

pxi = γimvxi = pxf = γfmvxf (see the attactments)

the particle will acquire a velocity in the y

direction, and vxf <vxi. The x-component of the velocity, and thus the x-component of the momentum

must decrease.

At the equator, near the surface of the Earth, the magnetic field is approximately 50.0 μT northward, and the electric field is

MArishka [77]

Answer:

A) F_g = 8.9278 × 10^(-30)

B) F_e = 1.6 × 10^(-17) N upwards

C) F_m = 6.8 × 10^(-17) N downwards

Explanation:

A) Formula for gravitational force is;

F_g = m_e × g

m_e is mass of electron = 9.11 x 10^(-31) kg

F_g = 9.11 x 10^(-31) × 9.8

F_g = 8.9278 × 10^(-30) N downwards

B) Formula for Electric force is;

F_e = qe

q is charge on electron = 1.6 × 10^(-19) C

E is electric field = 100 N/C

F_e = 1.6 × 10^(-19) × 100

F_e = 1.6 × 10^(-17) N upwards

C) Magnetic force is given by the formula;

F_m = qVB

q is charge on electron = 1.6 × 10^(-19) C

V is velocity given as 8.50 × 10^(6) m/s

B is magnetic field = 50.0 μT = 50 × 10^(-6) T

F_m = 1.6 × 10^(-19) × 8.50 × 10^(6) × 50 × 10^(-6)

F_m = 6.8 × 10^(-17) N downwards

How should a line look like if an object is at rest(stopped) on a distance-time graph?

guajiro [1.7K]

If an object is at rest, then its distance doesn't change as time goes on.

On the graph, the points for each time are all at the same distance. They form a horizontal line.
