Answer:
its true that Scientific endeavor is driven by both simple curiosity as well as societal demands.
Explanation:
When a scientist has a curiosity about something he carried out a research. and when their is a demand of something in society that time scientific research is carried out. Therefore its true that a scientific endeavor is driven by simple curiosity or societal demand.
For example
in society, there is demand of a medicine which can completely kill the cancer and a scientist has curiosity to know how to kill cancer cell. In this way a scientific endeavor for cancer medicine can be carried out by both simple curiosity as well as societal demands.
The force of earth gravity on the space craft is 1.19 N
\begin{array}{c}
F = \frac{{GMm}}{{{{\left( {r + h} \right)}^2}}}\\
= \frac{{6.67 \times {{10}^{ - 11}} \times 6 \times {{10}^{24}} \times 1050}}{{{{\left( {\left( {6400 + 12800} \right) \times {{10}^3}} \right)}^2}}}\\
= 1.139\;{\rm{N}}
\end{array}$
Hence, the force of gravity on the space craft is 1.19 N.
It's hard to tell exactly what's happening in that 110 cm that you marked over the wave. What is under the ends of the long arrow ? How many complete waves ? I counted 4.5 complete waves ... maybe ?
If there are 4.5 complete waves in 110cm, then the length of 1 wave is (110/4.5)=24.44cm.
Frequency = speed/wavelength
Frequency = 2m/s /0.2444m
Frequency = 8.18 Hz
Answer:
As per law of conservation of momentum
1 × 10 = 50× v
v = 1/5 m/S
Or
20 cm/s
