36/12= 3 3 IS THE AMOUT OF HALFLIVES
ONE HALF LIFE = 300
TWO HALF LIFE = 150
THREE HALF LIFE = 75
*Divide 600 three times
Answer:
The measurement which is the most precise is 104.6 °C.
Explanation:
The measurement which is most precise must be very close to the actual value of the temperature.
Thus, the unit which have less value of the |Δx| (error) must be most precise.
Thus,
Actual value = 105.1 °C
Value = 103.7 °C
<u>|Δx| = 1.4 °C</u>
Value = 108.4 °C
<u>|Δx| = 3.3 °C</u>
Value = 105.8 °C
<u>|Δx| = 0.7 °C</u>
Value = 104.6 °C
<u>|Δx| = 0.5 °C</u>
<u>Thus, The measurement which is the most precise is 104.6 °C.</u>
Both distance between and mass of the 2 objects.
Answer:
17.3 m
Explanation:
Given that,
Mass of a hammer is 0.58 kg
Velocity with which the hammer slides is 6.69 m/s at constant speed.
The roof makes an angle of 18 ◦ with the horizontal, and its lowest point is 18.2 m from the ground. We need to find the horizontal distance traveled by the hammer between the time is leaves the roof of the house and the time it hits the ground. Firstly, we will find the time taken by the hammer when it reaches ground in vertical direction.

Putting all the values,

Neglecting negative value,
To find horizontal distance, multiply 2.72 s with the horizontal component of velocity.
