Here, you need to use your "Protractor" as it is given in the question, but we can calculate the value with the help of our mathematical calculation too:
[ Protractor can be use only in real life, not here ]
Draw an imaginary line from initial position to final position.
Now, In that triangle, tan x = P/B
tan x = 1.4 / 2
tan x = 0.70
x = tan⁻¹ (0.70)
x = 35 [ tan 35 = 0.70 ]
In short, Your Answer would be 35 degrees
Hope this helps!
Answer:
1.32142x10^-3 Gy
Explanation:
Mass m = 63kg
Time t = 5.0s
Beta energy = 1.5x19^-13J
1 Ci = 3.7x10¹⁰
3.0Ci = 3x3.7x10¹⁰
= 11.1x10¹⁰decay/s
We have a total of 11.1x10¹⁰ beta particles produced per second
The question says there is 100% absorption
Et = (11.1x10¹⁰)x5x1.5x10^-13
= 0.08325
The radiation dose = Et/m
= 0.08325/63 kg
= 0.001321428J/kg
= 0.001321428 grays
Or 1.32142x10^-3 Gy
Power is the rate at which energy is consumed. When 1 J of energy is consumed in one second, the power consumed is 1 watt.
The microwave consumes 1.5 kJ of energy.
In joules, the energy consumed is 1500 J
Here, E is the energy consumed in time interval <em>t.</em>
The power rating of the microwave is therefore,
Thus, the power rating of the oven is 1500 W or 1.5 kW
g will be equal to 9.775, f=mg
So m= f/g
=99.95
First blank is radiator
Second blank is radiator
