Constant velocity means the netto force = 0, therefore F(gravity) = F(astronaut).
175N divided by 87,5kg = 2.00kg/N
Answer:
Warming signs before fad diet includes:
1. When a special type of diet is recommended for weight loss.
2. When quick weight loss is promised instead of advice on the need to exercise, eat healthy foods including fruits and vegetables, and adopt a good feeding behavior.
3. Promises rapid weight loss in a short period of time.
After taking the fad diet the following might be experienced:
1. Constipation.
2. Weakness and fatigue.
3. More accumulation of fats in the body in the long run after a short term normal BMI (Body mass index).
4. Lower metabolic rates over time.
Explanation:
weight loss is a practice adopted by people for various reasons ranging from the desire to stay healthy to, ability to pursue a career that requires a good Body Mass Index. For instance, A BMI (Body mass index) which is equal to a person's weight (kg) / (height(m))^2 of 30 and higher is considered obese.
Fad diet which may give a temporary result of weight loss is not considered totally healthy as it doesn't capture the need to eat a healthy balanced diet instead focuses on more routine consumption of a particular kind of diet.
A healthy weight loss plan captures the need to exercise, reduce body fats while eating healthy. Eating fruits, vegetables are also encouraged.
Answer: Thermal Energy
Explanation: I know this answer is correct because I had to look in my notebook for the definition
In my own words: Thermal Energy is the energy coming from heat which means it is generated by the movement of tiny particles with different objects.
Hope this helps! :)
Answer:
An electric chemical cell is not always needed to have a power circuit. But every other part is.
Answer: 9
Explanation:
Kinetic energy is the energy possessed by a moving object. It is measured in joules, and depends on the mass (m) of the object and the speed (v) by which it moves i.e K.E = 1/2 x mass x velocity^2
So, car is traveling 120 km/h
KE = 1/2x m x (120 km/h)^2
KE = 0.5 x m x 14400
KE1 = 7200m
So, car is traveling 40 km/h
KE = 1/2x m x (40 km/h)^2
KE = 0.5 x m x 1600
KE2 = 800m
Now, divide the value of kinetic energy obtained during 120 km/h by that obtained during 40 km/h
i.e 7200m / 800m
= 9
Thus, the kinetic energy will be 9 times more at a speed of 120 km/h than at 40 km/h
