How much work does it take to accelerate from 5 m/s to 10 m/s?

Physics
1 answer:
REY [17]3 years ago
3 0

Answer:

KE (5) = 1/2 M V^2 = 25/2 M

KE (10) = 1/2 M V^2 = 100/2 M

KE (10) - KE (5) = M/2 (100 - 25) = 75/2 / M

An object traveling at 10 m/s has 4 times the kinetic energy as an object traveling at 5 m/s

Total work would depend on the mass being accelerated

Two long, parallel wires are separated by a distance of 2.2 cm. The force per unit length that each wire exerts on the other is
VikaD [51]

Answer:

i_2 = 7.6 A

Explanation:

As we know that the force per unit length of two parallel current carrying wires is given as

F = \frac{\mu_o i_1 i_2}{2\pi d}

here we know that

F = 3.6 \times 10^{-5} N/m

i_1 = 0.52 A

d = 2.2 cm

now from above equation we have

3.6 \times 10^{-5} = \frac{4\pi \times 10^{-7} (0.52)(i_2)}{2\pi (0.022)}

3.6 \times 10^{-5} = 4.73 \times 10^{-6} i_2

i_2 = 7.6 A

Why can rock avalanches move downslope at speeds exceeding 200 km/hr (125 mi/hr)?
Sati [7]

Rock avalanches move downslope at speeds exceeding 200 km/hr (125 mi/hr) because when the soil expands and compresses, it lifts certain particles and drops them downslope a short distance.

Landslides are the common name for soil or rock avalanches. The most frequent type of avalanche, snowslides, can travel downhill more quickly than a skier. When an unstable snow mass detaches from a slope, a snow avalanche starts.

Rock avalanches are caused by the rapid breakup of initially intact, highly fast-moving rock masses during transportation. In mountainous areas, rock avalanches, which are unexpected rock slope failures marked by high velocities, lengthy runouts, and massive volumes, are among the most deadly and costly geological hazards.
