Physics
1 answer:
PSYCHO15rus [73]3 years ago
6 0

Answer:

Not including a sedimentary cover of variable thickness and composition, the oceanic crust consists of three layers: (1) a relatively thin uppermost volcanic layer of basaltic lavas known as mid-ocean ridge basalts (MORB) erupted on the seafloor; (2) a thicker layer of more coarsely crystalline, intrusive basaltic

A 50-cm wire placed in an east-west direction is moved horizontally to the north with a speed of 2.0 m/s. the horizontal compone
Strike441 [17]

When a wire is moved inside uniform magnetic field then its free electrons will experience magnetic force on it due to which wire will have potential difference at its ends.

Now here we will have magnetic field due to earth and wire is moving in this constant field so induced emf is given by formula

EMF = v.(B x L)

given that

B = 25\mu Tj - 50\mu Tk

v = 2 m/s j

L = 0.50 m (-i)

now by using the above formula we will have

EMF = 2(j) .(25\mu j - 50\mu k) x (-0.50 i)

EMF = 2(j) .(12.5\mu k + 25\mu j)

EMF = 50 \mu Volts

Describe how the life cycle of a low-mass star differs from the life cycle of a high-mass star. PLZZZZ ANSWER FAST
Alex Ar [27]
 <span>As the core collapses, the </span>outer<span> layers of the star are expelled. A planetary nebula is formed by the </span>outer <span>layers. The core remains as a white dwarf and eventually cools to become a black dwarf. that is what would happen to a star with a low mass like our sun also the life time of a star depends on it's mass. A larger mass star will colapse and turn into a black hole.</span><span>

Two large parallel plates are 2.0 cm apart. The strength of the electric field between them is 50.0 N/C . What is the difference
diamong [38]

Express the distance in meters:

d= 2 cm =0.02 m

V = Ed = 50 N/C * 0.02 m = 1 N/C m = 1 V = +1.0 V
