In a laboratory, it is often convenient to make measurements in centimeters and grams, but SI units are needed for calculations.

zheka24 [161]

Answer:

(a) 0.92 cm= 0.092 m.

(b) 141.64 g=0.14164 kg.

(c) 15. 8 cm³=0.0000158 m³

(d) 63.6 g/cm³= 63600 kg/m³

Explanation:

The International System of Units, abbreviated S.I., also called the International System of Measurements is a system of measurements in which its units are based on fundamental physical phenomena. The units of the S.I. They are the international reference for the indications of all measuring instruments.

The International System of Units (SI) arose from the need to unify and give coherence to a great variety of unit subsystems.

The International System of Units consists of seven basic units, also called fundamental units, which define the corresponding fundamental physical quantities and which allow any physical quantity to be expressed in terms or as a combination of them. The fundamental physical quantities are complemented by two more physical quantities, called supplementary ones.

By combining the basic units, the other units are obtained, called units derived from the International System, and which allow defining any physical quantity.

(a) The SI unit of length is the meter. Being 1 cm = 0.01 m, then 0.92 cm= 0.092 m.

(b) The SI unit of mass is kg. Being 1 g = 0.001 kg, then 141.64 g=0.14164 kg.

(c) Being 1 cm³ = 0.000001 m³, then 15. 8 cm³=0.0000158 m³

(d) Being 1 g/cm³= 1000 kg/m³, then 63.6 g/cm³= 63600 kg/m³

A disk is free to rotate about an axis perpendicular to the disk through its center. If the disk starts from rest and accelerate

garri49 [273]

Answer:

(C) 16 radians

Explanation:

The angular displacement is given by the following equation:

$\Delta \theta=\omega_i t+\frac{1}{2}\alpha t^2$

Here

$\Delta \theta$ Is the angular displacement of the body at the indicated time (t).

$\omega_i$ Is the angular velocity of the body at the initial moment.

$\alpha$ Is the angular acceleration of the body.

The disk starts from rest, so $\omega_i=0$

Replacing the given values:

$\Delta \theta=\frac{1}{2}(2\frac{radians}{s^2})(4s)^2\\\Delta \theta=16 radians$

In electrical work, the symbol W is used to indicate

kirill115 [55]

The question has no answer, sad to say. The symbol W is used as a shortcut of saying "watts" which refers to the unit of power.
The symbol for Voltage = V
The symbol for resistance = R (unit is Ohms)
The symbol of electromagnetic force = N (for Newton)
The symbol or current = I (unit is A for amperes)
