riadik2000 [5.3K]

Option C

In nuclear fission and fusion the mass defect is the mass lost during the reaction that is converted into energy

<u>Explanation:</u>

Mass defect is the contrast within the estimated mass of the released system and the empirically estimated mass of the nucleus. The nuclear binding energy is acknowledged as mass, and that mass enhances "missing".

This missing mass is described as a mass defect, which is nuclear energy, also acknowledged as the mass discharged from the reaction as any trajectories. The mass defect of a nucleus depicts the mass of the energy adhesive of the nucleus and is the variation amidst the mass of a nucleus and the entirety of the masses of the nucleons of which it is comprised.

A space probe is coasting through space at a steady speed of 100p feet per second. the booster rocket fires for 1/2 seconds so t
aleksandr82 [10.1K]

Answer:

Acceleration: 9800 ft/s^2

Explanation:

The acceleration of an object is equal to the rate of change of velocity:

a=\frac{v-u}{t}

where

u is the initial velocity

v is the final velocity

t is the time taken for the velocity to change from u to v

For the space probe in this problem, we have:

u = 100 ft/s (initial velocity)

v = 5000 ft/s (final velocity)

t = 0.5 s (time taken)

Therefore, the acceleration is

a=\frac{5000-100}{0.5}=9800 ft/s^2

A 0.366 kg metal cylinder is placed inside the top of a plastic tube, the lower end of which is sealed off by an adjustable plun
DochEvi [55]

Answer:

a = 32.6 m/s^2

Explanation:

As we know that pressure between the cylinder and plunger is increased by 1.59 times

So this will make a net force upwards on the cylinder which is given as

F = \Delta P A

now we will have

\Delta P = P_2 - P_1

Here initial pressure is given as

P_1 = P_o + \frac{mg}{A}

now new pressure is given as

P_2 = 1.59 P_1

so we have force on the cylinder given as

F = P_2A - mg - P_oA

F = 1.59(P_0 + \frac{mg}{A})A - (mg + P_0A)

F = 0.59(1.01 \times 10^5 \times \pi(7.24 \times 10^{-3})^2  + 0.366(9.81))

F = 11.93 N

now the acceleration is given as

F = ma

11.93 = 0.366 a

a = 32.6 m/s^2
