No it doesn't depend on the mass of the car
the maximum speed will be = √urg
√0.65*90*9.8 = v
which comes around 24 m/s

Alternating current changes the ____ of the current flow
Anuta_ua [19.1K]

Answer:

Direction

Explanation:

There are two types of electric current:

- DC (Direct current): in a direct current, the direction of the flow of the current is constant; this means that it does not change. This means that the potential difference supplied has always the same direction, so that the electrons travel always in the same direction through the circuit

- AC (Alternating current): in an alternating current, the direction of the flow of the current is constantly reverses. This means that the direction of the potential difference supplied constantly changes, therefore the electrons travel half the time in one direction and half the time in the opposite direction.

Which of the following is NOT a reason why exercise routines should have clearly stated goals?
denis-greek [22]
  • Goals allow individuals to track their progress against others is not a reason behind exercise routines have clearly stated goals.
  • Specificity means an exercise program should have end goals that target specific areas. This statement is true.

Further Explanation:

The fitness program helps in achieving good health. To start fitness program we have to make fitness goals, create a healthy diet. Physical fitness is the capability of a body to perform daily activity.

Physical fitness helps us to prevent heart disease, lung cancer, stroke, and type II diabetes. Progress of a fitness program is very slow it takes time. It is more difficult to maintain a program for a long time with the same enthusiasm. We can set the goal and check whether we are progressing or not. If the goals of an individual are successfully attain then an individual gets motivated for the next day. When the goals are not achieved, it is important to check for the part that can be improved. We mainly set goals for own concerns, satisfaction and achievement. Goals are not related to others.

Specificity is occurring in a specific reaction that occurs as a result of exercise program. Specificity increases the long-term adaptations to occur with progressive overload. Specificity—a focus on particular movements, muscles, velocity and energy systems —drives the gains you make in training and practice. If an individual doesn't intentionally train for something, it may not occur.

Specificity is decreased when an individual is not focusing on the goal. Specificity helps in achieving their goals. Then, an individual have to set a fresh goal for the assessment and train themselves for that particular goal. Individuals who are involved in fitness programs should set goals and weekly asses the progress by the fitness evaluation test. If we achieve our goals we should give our self-reward.
