Answer:
A compass can detect a magnetic field and show its direction. Iron filings can show the shape of a magnetic field. A gaussmeter can detect a field and indicate its strength.
Explanation:
Explanation:
The force would be net positive.
Answer:
A fluid's viscosity strongly depends on its temperature. Along with the shear rate, temperature really is the dominating influence
Explanation:
The higher the temperature is, the lower a substance's viscosity is. Consequently, decreasing temperature causes an increase in viscosity.
Explanation:
<em><u>Newton's First Law ,</u></em>
F = ma
a = m/F
a = 68 / 59
a = 1.15 m/s2
