Answer:
128Nm
Explanation:
w=d*F
w=3.2m*40N
w=128Nm
plz mark brianliest if its correct....
Answer:
To minimize the practical errors and improve the accuracy.
Explanation:
- Scientists take several measurements and use the average of all the measured values to minimize the practical errors due to unavoidable circumstances and be close to the true value.
- True value is the actual value of a measured parameter without any error, it is the value which is proposed in the design of a certain object.
- Variations may occur in the measurement due to wear and tear, dust and air pressure. It is almost impossible to create ideal surrounding for the measurement procedure.
<span>Answer:
Correct answer is
just add the two kinetic energies;
E = (1/2)mv^2 + (1/2)mv^2</span>
So i converted everything first;
<span>7.0 C ---> 280 K </span>
<span>49 mL---> 0.049 L </span>
<span>74mL---> 0.074 L </span>
<span>THEN I tried setting it up by the combined law formula which is P1V1/T1=P2V2/T2 </span>
