Answer:

B < D < A < C

Explanation:

Kinetic energy depends on the mass and the square of the velocity of the body. A body in motion has kinetic energy.

A. m = 12000 kg

v = 15 m/s

K.E. = 0.5 mv²

= 0.5 (12000 kg) (15 m/s)²

= 1,350,000 J

B. m = 10,000 kg

v = 0

K.E. = 0 J

C. m = 15 kg

v = 1000 m/s

K.E.=0.5 mv²

= 0.5 (15 kg) (1000 m/s)²

= 7,500,000 J

D. m = 100 kg

v = 5 m/s

K.E.=0.5 mv²

= 0.5 (100 kg) (5 m/s)²

= 250 J

In increasing order of kinetic energy:

B < D < A < C

A river flows due east with a speed of 3.00 m/s relative to earth. The river is 80.0 m wide. A woman starts at the southern bank

babymother [125]

Answer:

48 m

Explanation:

As she travels at the rate of 5m/s due north, the amount of time it would take for her to cross the 80m wide river would be

t = 80 / 5 = 16 seconds

This is also the time it takes for the river to push her to the east side at the rate of 3m/s. So after 16 seconds, she would reach the opposite point at a horizontal distance from her starting of

s = 16*3 = 48 m

Energy from various sources is considered to have been derived from sun.Do you agree?Do justify.

Kruka [31]

Yes! with out the sun plants and animals wouldnt live right? therefore they get energey wich is passed on by food

In order to place a satellite into orbit, it requires enough fuel to supply the necessary mechanical energy. Into what types of

nexus9112 [7]

When a satellite is revolving into the orbit around a planet then we can say

net centripetal force on the satellite is due to gravitational attraction force of the planet, so we will have

$F_g = F_c$

$\frac{GM_pM_s}{r^2} = \frac{M_s v^2}{r}$

now we can say that kinetic energy of satellite is given as

$KE = \frac{1}{2}M_s v^2$

$KE = \frac{GM_sM_p}{2r}$

also we know that since satellite is in gravitational field of the planet so here it must have some gravitational potential energy in it

so we will have

$U = -\frac{GM_sM_p}{r}$

so we can say that energy from the fuel is converted into kinetic energy and gravitational potential energy of the satellite

Two identical charges q placed 2.0 mapart exert forces of magnitude 4.0 N on each other What is the value of the charge q? a) q

katen-ka-za [31]

Answer:

c) $4.2*10^{-5}C$

Explanation:

Coulomb's law says that the force exerted between two charges is inversely proportional to the square of distance between them, and is given by the expression:

$F=\frac{kq_{1}q_{2}}{r^{2}}$
