Which of the following groups of instruments do tipanu, aruding and beberek fall under?.
Answer:
chordophone is the anser
Explanation:
Block a rests on top of block b as shown in (figure 1). The table is frictionless but there is friction (a horizontal force) between blocks a and b. Block b has mass 6. 00 kg and block a has mass 2. 00 kg. If the horizontal pull applied to block b equals 12. 0 n, then block b has an acceleration of 1. 80 m/s2.
The acceleration of block A is 0.6 m/s².
Net force on the blocksThe net force on the blocks is determined by applying Newton's second law of motion.
∑F = ma
Acceleration of bock AThe acceleration of block A is calculated by applying Newton's second law of motion as follows;
[tex]F_a + F_b = F\\\\F_a = F-F_b\\\\m_a a_a = F- m_ba_b\\\\a_a = \frac{F- m_ba_b}{m_a}[/tex]
Where;
Mb is mass of block B = 6 kgMa is mass of block A = 2 kg[tex]a_b[/tex] is acceleration of block B = 1.8 m/s²[tex]a_a[/tex] is the acceleration of block A = ?[tex]a_a = \frac{12\ - \ 6 \times 1.8}{2} \\\\a_a = 0.6 \ m/s^2[/tex]
Thus, the acceleration of block A is 0.6 m/s².

A car’s engine generates 100,000 w of power as it exerts a force of 10,000 n. How long does it take the car to travel 100 m?.
Answer:
10
Explanation:
Engine generates 100,000\ W power
Force exerts F=10,000\ N
Distance traveled d=100\ m
work done is given by
W=F\cdot d\\W=10,000\times 100\\W=10^5\ J
Also, Energy is given as
\Rightarrow E=P\cdot t
Insert the values
\Rightarrow 10^6=100,000\times t\\\\\Rightarrow t=\dfrac{10^6}{10^5}\\\\\Rightarrow t=10\ s
What is true when the units in ending inventory increase during the year.
The true option is : Net income is higher for absorption costing than for variable costing.
What is Net income?Net income is the actual amount left to an individual or a company, after taken out all other expenses.
Here, absorption cost are those cost that includes the costs like variable costs as well as the overhead costs which are fixed in nature.
This means that an increase in the closing stock balance, the net income for the absorption costing shows more than that of the variable costing.
Hence, the net income for absorption costing is higher than variable costs when the closing inventories increases throughout the year.

The diameter of a semicircular pond is 7 m. Find its perimeter.
Answer:
Approximately 18 m
Explanation:
Hi there!
What we need to do to solve this question is the following:
1. Find the circumference of the circle, as if the pond is CIRCULAR and NOT SEMICIRCULAR
2. Divide the circumference in half to find the length of the round part of the semicircle
3. Add 7 m to that value to get the straight side of the semicircle
1. Find the circumference of the circle (C)
[tex]C=\pi d[/tex] where d is the diameter
Plug in the diameter 7 m
[tex]C=\pi (7)\\\\C=7\pi[/tex]
We're not going to solve this just yet, but we will in the end. This is so that we can get a more precise answer.
2. Halve the circumference

Which statement best explains the working principle of an electric motor.
Answer:
The principle of an electric motor is based on the current-carrying conductor which produces magnetic field around it. A current-carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
Explanation:
In this exercise we have to use the knowledge of electric motors and explain that they work through a closed circuit and a source.
What are electric motors?Electric motors are electrical machines that transform electrical energy into mechanical energy. There are many types of electric motors, and we can basically separate them into three large groups which are direct current motors, alternating current motors and universal motors.
In a simpler way, we can say that they are motors that use a closed system that has a source and an electric current.
