Physics
1 answer:
MrMuchimi1 year ago
6 0

The density of a cube that has a mass of 12. 6 and a measured  length of  4.1 cm is 0.18 kg/cm³

Density=mass/volume

mass=12.6

volume=68.9

density=12.6/68.9

density=0.18 kg/cm³

Density is defined as a material substance's mass per unit volume. Density is described by the equation d = M/V, where d stands for density, M for mass, and V for volume. Grams per cubic centimeter is the unit of measurement for density. For instance, compared to Earth's density of 5.51 grams, water has a density of 1 grams per cubic centimeter . Another way to express density is in kilograms per cubic meter (in meter-kilogram-second or SI units), It is easy to determine the relationship between mass and volume using density. For instance, the formula for determining a body's mass is M = Vd, while the formula for determining a body's volume is V = M/d.

What are some issues that governments must consider before passing conservation policies? Check all that apply.
Otrada [13]

Answer: cost to implement conservation policies

environmental implications

benefit versus the cost

Explanation:

The conservation policies involves certain instructions which are required to be followed by the human society at all levels so as to conserve resources and protect them for future. The following are the issues which government should be consider before passing the conservation policies this includes:

1. cost to implement conservation policies : The procedure and expenditure for the implementation of the policies should be under control of the desired budget so that the plan can be efficiently executed.

2.environmental implications : The government should be concerned about the implication of the policies on the environment. For example the preservation of an endangered species in control condition from an ecosystem can disturb the overall balance of an ecosystem.

3.benefit versus the cost: The government should concern before expending on the implementation of the policies the benefits and costs of the desired policies.

A metal block of mass 265 g rests at a point 2.4 m from the center of a horizontal rotating wooden platform. The coefficient of
FrozenT [24]

Answer:

The minimum angular velocity of the platform what whould the block slides away is w= 2.26 rad/s.

Explanation:

m= 0.265 kg

r= 2.4 m

μ= 0.257

g= 9.8 m/s²

W= m * g

W= 2.597 N

Fr= μ * W

Fr= 0.66 N

∑F = m * ac

W+Fr = m * ac

(W+ Fr) / m = ac

ac= 12.29 m/s²

ac= w² * r

√(ac/r)= w

w= 2.26 rad/s

A driven RLC circuit is being driven by an AC emf source with a maximum current of 2.75 A and maximum voltage of 150 V. The curr
weqwewe [10]

Answer:

(a). Z = 54.54 ohm

(b). R = 36 ohm

(c). The circuit will be Capacitive.

Explanation:

Given data

I = 2.75 A

Voltage = 150 V

\phi = 0.85 rad = 48.72°

(a). Impedance of the circuit is given by

Z = \frac{V}{I}

Z = \frac{150}{2.75}

Z = 54.54 ohm

(b). We know that resistance of the circuit is given by

R = \frac{Z}{\sqrt{1 + \tan^{2}\phi } }

Put the values of Z & \phi in above formula we get

R = \frac{54.54}{\sqrt{1 + \tan^{2} ( \ 48.72) } }

R = 36 ohm

(c). Since the phase angle is negative so the circuit will be Capacitive.
