Answer:
the scalar quantities in this exercise are: 3 kg rice, 2 liters of milk and 5 face masks, the rapides 3 m / s
the vector quantities are: the displacement to the supermarket and the drugstore
Explanation:
For this problem we are asked to find scalar quantities and vector quantities.
A scalar quantity is one that is described by a number with its units
A vector quantity is that described by a number (module), a direction and a sense, that is, they must be represented by a vector
the scalar quantities in this exercise are: 3 kg rice, 2 liters of milk and 5 face masks, the rapides 3 m / s
the vector quantities are: the displacement to the supermarket module 50 m directional 30º sense with respect to the horizontal.
The displacement to the drugstore modulo 70 m direction 150º with respect to the supermarket
Answer:
1.40071 m/s
Explanation:
m = Mass of object = 100 g
v = Velocity of object
h = Height of drop = 10 cm
g = Acceleration due to gravity = 9.81 m/s²
Here, the loss of potential energy is equal to the gain in kinetic energy as energy is conserved
The speed of the object at the instant that the rod is horizontal is 1.40071 m/s
Headache
Flushed face
Excessive sweating
Struggling to perform
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.

Weight is defined as a body's mass multiplied by its acceleration due to gravity.
Test Book's weight on mars = 8.1 N.
Weight = (mass) x (gravity)
= (2.2 kg) x (3.7 m/s^2)
= 8.1 newtons
