Answer:
Force exerted by car on truck will be 6000 N in opposite direction
Explanation:
It is given that mass of the car is one quarter of the mass of the truck
Force exerted by the truck on the car is 6000 N
We have to find the force exerted by car on the truck
According to newtons third law for any action there is equal and opposite reaction
So force exerted by car on the truck will be equal to 6000 N in opposite direction

Answer:
The thyroid is a butterfly-shaped gland that sits low on the front of the neck.It plays a major role in the metabolism, growth and development of the human body
Explanation:
The physiologic function affected by altered thyroid function are:
1. It is likely that all cells in the body are targets for thyroid hormones
2. It stimulates diverse metabolic activities most tissues, leading to an increase in basal metabolic rate
3. Thyroid hormones are clearly necessary for normal growth
Thyroid hormones increases heart rate, cardiac contractility and cardiac output. They also promote vasodilation (widening of blood vessels), which leads to enhanced blood flow to many organs. Central nervous system: Both decreased and increased concentrations of thyroid hormones lead to alterations in mental state.
There do not seem to be organs and tissues that are not affected by thyroid hormones
Answer:
B) 3.33 m/s²
Explanation:
Given that,
The initial velocity of Juan, u = 10 m/s
Final velocity of Juan, v = 60 m/s
Time taken, t = 15 s
The acceleration is given by the relation
a = v-u/t m/s²
Substituting in the above equation
a = 60 - 10 / 15
a = 3.33 m/s²
Hence, the acceleration of the Juan is, a = 3.33 m/s²
