What is the density of 25 grams
Karolina [17]

If you only have one number, then the density of it is like one scis, or one tweez, or the sound of one hand clapping, or one pant.

A spring balance consists of a pan that hangs from a spring. A damping force Fd = −bv is applied to the balance so that when an
Citrus2011 [14]

Answer:

b ≈ 64 Kg/s

Explanation:

Given

Fd = −bv

m = 2.5 kg

y = 6.0 cm = 0.06 m

g = 9.81 m/s²

The object in the pan comes to rest in the minimum time without overshoot. this means that damping is critical (b² = 4*k*m).

m is given and we find k from the equilibrium extension of 6.0 cm (0.06 m):

∑Fy = 0 (↑)

k*y - W = 0    ⇒   k*y - m*g = 0   ⇒   k = m*g / y

⇒   k = (2.5 kg)*(9.81 m/s²) / (0.06 m)

⇒   k = 408.75 N/m

Hence, if

b² = 4*k*m    ⇒     b = √(4*k*m) = 2*√(k*m)

⇒     b = 2*√(k*m) = 2*√(408.75 N/m*2.5 kg)

⇒     b = 63.9335 Kg/s ≈ 64 Kg/s

Jacob drives his car 7 km east. He stops for lunch, then drives 5 km south before driving 2 km east. What distance did he cover?
Varvara68 [4.7K]

Option (d) is correct.

Distance is the total path length covered by the object.

so, for distance, we add all the path lengths

Here the total distance =7+5+2 =14 km
