Answer:
31677.2 lb
Explanation:
mass of hammer (m) = 3.7 lb
initial velocity (u) = 5.8 ft/s
final velocity (v) = 0
time (t) = 0.00068 s
acceleration due to gravity (g) 32 ft/s^{2}
force = m x ( a + g )
where
- m is the mass = 3.7 lb
- g is the acceleration due to gravity = 32 ft/s^{2}
- a is the acceleration of the hammer
from v = u + at
a = (v-u)/ t
a = (0-5.8)/0.00068 = -8529.4 ( the negative sign showa the its decelerating)
we can substitute all required values into force= m x (a+g)
force = 3.7 x (8529.4 + 32) = 31677.2 lb

The sun?? It stays in one spot, but from our point of view, it travels around the earth...
Answer:
the thermistor temperature = 
Explanation:
Given that:
A thermistor is placed in a 100 °C environment and its resistance measured as 20,000 Ω.
i.e Temperature
Resistance of the thermistor 
20,000 ohms
Material constant 
= 3650
Resistance of the thermistor 
= 500 ohms
Using the equation :
Taking log of both sides
Replacing our values into the above equation :
Thus, the thermistor temperature =
The sun is the primary source of light. Other artificial sources are light bulb, torch light and some others. Thats all i can think of.
