Answer:

to check for errors.

Explanation:

since some of the components of the scale are metallic, they are prone to rusting which would cause error in reading of the scale so there is organized checking if the scale to correct that.

hope it helps .

The price of many products in the market is "__ dollars per pound", or "___ rupees for 100 grams".

The scale in the market is used to measure how many pounds or how many grams the customer is taking home, and how much he should pay for it. Sometimes the scale is used to weigh the "money" too.

If the scale is not showing accurate weight, then the shopkeeper is either cheating himself or cheating the customer. Fair and honest business is not possible without accurate scales.

There are nearly 100 verses in the Bible regarding this. Leviticus 19:35 is the first one.

A(n) 12500 lb railroad car traveling at 7.8 ft/s couples with a stationary car of 7430 lb. The acceleration of gravity is 32 ft/

navik [9.2K]

To solve this problem we will apply the concepts related to the conservation of momentum. That is, the final momentum must be the same final momentum. And in each state, the momentum will be the sum of the product between the mass and the velocity of each object, then

$\text{Initial Momentum} = \text{Final Momentum}$

$m_1u_1 +m_2u_2 = m_1v_1+m_2v_2$

Here,

$m_{1,2}$ = Mass of each object

$u_{1,2}$ = Initial velocity of each object

$v_{1,2}$ = Final velocity of each object

When they position the final velocities of the bodies it is the same and the car is stationary then,

$m_2u_2 = (m_1+m_2)v_f$

Rearranging to find the final velocity

$v_f = \frac{m_2u_2}{ (m_1+m_2)}$

$v_f = \frac{ 12500*7.8}{ 12500+7430}$

$v_f = 4.8921ft/s$

The expression for the impulse received by the first car is

$I = m_1 (v-u)$

$I = \frac{W}{g} (v-u)$

Replacing,

$I = \frac{12500}{32.2}(4.89-7.8)$

$I = -1129.65lb\cdot s$

The negative sign show the opposite direction.

igomit [66]

Answer:

Pseudoscience

Explanation:

Predicting future events in a person's life based on the lines on the palm of the hand is an example of Pseudoscience. A pseudoscience is a false science that makes claims based on faulty or nonexistent scientific evidence and often characterized by contradictory, excessive claims, etc. These types of Pseudoscientific beliefs are common due to widespread "scientific illiteracy among different societies.
