How does gravitational pull affect planets with the same mass but different distance from the sun?

Canada’s northern territories experience "midnight sun," meaning what?.

Leona [35]

Answer:

Explanation: The term "midnight sun" refers to the consecutive 24-hour periods of sunlight experienced in the north of the Arctic Circle and south of the Antarctic Circle. Other phenomena are sometimes referred to as "midnight sun", but they are caused by time zones and the observance of daylight saving time.

In what kind of exercise would you use the FITT model?

Solnce55 [7]

Answer:

The correct answer is:

Cardio exercise (B)

Explanation:

The frequency, intensity, time and type (FITT) model is a model is planning exercises that incorporate the four elements to be considered when choosing a personal goal and fitness level. Cardiovascular exercises mainly involves aerobic exercises that are aimed at strengthening the heart and lungs and making the working muscles more efficient at the use of oxygen. They also increase stroke volume (volume of blood pumped per minute) and resting heart rate. The following are what the model entails and how they fit best with cardio exercises:

Frequency: This has to do with how often exercises will be done. Depending on the goal cardio exercises are normally recommended as moderate exercises for five or more days a week, and intense cardio for three days a week
Intensity: This has to do with how hard you work during exercises. For cardio exercises, the heart rate monitor, perceived exertion and talk test are done to measure the intensity of the exercise
Time: This has to do with how long each exercise session will last. For cardio exercises, the recommendation is 30 to 60 minutes for each session.
Type: This is the actual activity that is chosen during the sessions, and it is chosen to avoid overuse injuries or weight loss plateus. The type of actvities for cardio includes exercises that are aimed at increasing the heart rate, like running, walking, cycling dancing etc.

Why does water’s high specific heat make it a good coolant for car radiators?.

Alexeev081 [22]

Answer:

Car radiators: Water is used as coolant car radiators. Due to its high specific heat capacity, it can absorb a large amount of heat energy from the engine of the car, but its temperature does not rise too high.

Which of the following statements are true about an object in two-dimensional projectile motion with no air resistance? (There c

ki77a [65]

Answer:

The correct answers are

The following statements are true about an object in two-dimensional projectile motion with no air resistance

D) The speed of the object is zero at its highest point.

E) The horizontal acceleration is always zero and the vertical acceleration is always a non-zero constant downward

Explanation:

A) The speed of the object is constant but its velocity is not constant.

False the vertical velocity increases on descent

B) The acceleration of the object is constant but its object is + g when the object is rising and -g when it is falling.

False, the acceleration is -g when the object is rising

C) The acceleration of the object is zero at its highest point.

False, the acceleration is constant in magnitude throughout the motion

D) The speed of the object is zero at its highest point.

True, the direction of motion changes at the highest point from hence the body comes to rest and the speed is zero

E) The horizontal acceleration is always zero and the vertical acceleration is always a non-zero constant downward

True, the horizontal acceleration has associated force during motion but the vertical acceleration is due to gravity which is constant downwards
