An 4-kg ball experiences a force and accelerates at a rate of 1.5 m/s.
ANTONII [103]

Answer:

6.0 N

Explanation:

The strength of a force is expressed as the magnitude of the force in Newton.

The formula to apply here is :

Force= mass * acceleration

F=ma

Mass, m = 4 kg

Acceleration = 1.5 m/s²

Force= 4 *1.5 = 6.0 N

Find the emitted power per square meter of peak intensity for a 3000 k object that emits thermal radiation.
Aleksandr [31]
According to Stefan-Boltzmann Law, the thermal energy radiated by a radiator per second per unit area is proportional to the fourth power of the absolute temperature. It is given by;
    P/A = σ T⁴ j/m²s 
Where; P is the power, A is the area in square Meters, T is temperature in kelvin and σ is the Stefan-Boltzmann constant, ( 5.67 × 10^-8 watt/m²K⁴)
Therefore;
Power/square meter = (5.67 × 10^-8) × (3000)⁴
                                 =  4.59 × 10^6 Watts/square meter

Through which medium would sound travel the fastest, water, a steel bar, or nitrogen gas explain
777dan777 [17]
It would travel faster through a steel bar, because sound waves travel by vibrating molecules in a medium. In solids, these molecules are spaced closer together, causing sound to travel faster through it. so that means the second fastest medium is liquid and the slowest is gas

A plant worker accidentally breathes some stored gaseous tritium, a beta emitter with maximum particle energy of 0.0186 MeV. The
andrey2020 [161]

Answer:

400 milli-rems

Solution:

As per the question;

Maximum energy of particle, E_{m} = 0.0186\ MeV

Weight, w = 1 kg

Energy absorbed, E = 4\times 10^{- 3}\ J

Now,

Equivalent dose is given by:

D_{eq} = \frac{E}{w}  =\frac{4\times 10^{- 3}}{1} = 4\times 10^{- 3}\ J/kg

1 Gy = 1 J/kg

Also,

1 Gy = 1\times 10^{5}\ milli-rems

Therefore,

Dose equivalent in milli-rems is given by:

D_{eq} = 4\times 10^{- 3}\times 1\times 10^{5} = 400\ milli-rems
