Answer:
Work done, W = 8 J
Explanation:
We have,
Force acting on the cart is 4 N
Cart covers a distance of 2 m
We need to find the work done by the cart. Work done by an object is given in terms of force and displacement. It can be given by :
So, the work done by the cart is 8 J.
Answer:
The paper does not catch fire when wrapped around aluminium pipe because aluminium absorbs the heat, so paper does not attain its ignition temperature.
Explanation:
The most precise method for determining the actual temperature of vaccines is to use a buffered temperature probe.
<h3>What is temperature?</h3>
Temperature directs to the hotness or coldness of a body. In clear terms, it is the method of finding the kinetic energy of particles within an entity.
Temperature is essential in all areas of Science right from Physics to Geology and also it is important in most parts of our everyday life.
The complete question is;
"What type of device should be used for measuring temperatures in a vaccine storage unit?"
A temperature monitoring system is required in every vaccine storage facility.
A buffered temperature probe offers the most precise storage unit temperature information, including a thorough history of how long a unit has been running beyond the advised temperature range.
Hence, the use of a buffered temperature probe is the most accurate way to measure actual vaccine temperatures.

Answer:
The bass has the lowest frequency ,it only causes vibrations but at a lower frequency
when a hole is made at the bottom of the container then water will flow out of it
The speed of ejected water can be calculated by help of Bernuolli's equation and Equation of continuity.
By Bernoulli's equation we can write
Now by equation of continuity
from above equation we can say that speed at the top layer is almost negligible.
now again by equation of continuity
here we have
now speed is given by
