Struggling to perform is not an early sign of heat illnesses.
There are times when the body system will be unable to dissipate heat effectively. When this happens, heat illness bounds to occur.
Also, heat illnesses tend to occur when the balance of salt and water in the body becomes unbalanced, the temperature rises unexpectedly or the sweet couldn't keep an individual cool.
Some of the early signs includes Headache, dizziness, Muscle cramps, weak pulse among other related symptoms.
Based on the above explanation, we can see that struggling to perform is not an early sign of heat illnesses.

Albert Einstein is a German scientist who developed the theory of relativity. He was born on the March 14, 1879, Ulm, Germany. This theory changed much in the way the scientists looked at the world and set the foundation for many modern inventions, including the nuclear bomb and the nuclear energy.

A quantity that has magnitude only is a scalar. In Physics, a quantity with only magnitude is called a scalar. Scalar quantities include distance, speed, mass, temperature, and energy. They are distinguished from vectors which have both magnitude and direction.
A scalar is a fundamental concept in mathematics and physics, representing a single quantity with magnitude but no direction. Scalars are characterized solely by their numerical value, such as speed or temperature. Unlike vectors, which have both magnitude and direction, scalars are concerned with the "how much" rather than the "where" or "in which direction." Scalars are used in various fields, from physics to mathematics and engineering, simplifying the description of quantities that don't involve direction, making calculations and analysis more straightforward.
A quantity that has magnitude only is referred to as a scalar. In Physics, quantities are typically classified into two types: scalars and vectors. A scalar quantity is defined by its magnitude alone, with no direction associated with it. Examples of scalar quantities include distance, speed, mass, temperature, and energy. On the contrary, a vector has both magnitude and direction. Hence, the correct answer to your question is scalar.

Answer:
scalar
Explanation:
A. 200 J
B. 330 J
C. 352 J
D. 220 J
Answer: Option (C) is the correct answer.
Explanation:
Work is defined as the energy required when force is applied in a certain direction.
The expression for work, force and distance is as follows.
W = F × d
where, W = work
F = force
d = distance
It is given that force applied to drag the box is 22 N and distance is 16 meters. Therefore, calculate work done as follows.
W = F × d
= 22 N × 16 meters
= 352 Nm (1 Newton meter = 1 joule)
or, W = 352 J
Thus, we can conclude that amount of work done is 352 J.
