What else can I help you with?
What is different about the motion of satellites that travel in elliptical paths compared to satellites that travel in circular paths?
Elliptical satellites don't have a constant speed, but circular satellites do
Is the speed of a wave constant?
The speed of a wave can vary depending on the medium through which it is traveling. In a given medium, the speed of a wave is typically constant if the conditions remain constant.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
No, if the instantaneous velocity of an object remains constant, then its instantaneous speed cannot change. Velocity is a vector quantity that includes both speed and direction. If the velocity is constant, it means both the speed and direction are constant.
What happends to the speed of a wave if the medium and temperature and pressure do not change?
The speed of a wave remains constant if the medium, temperature, and pressure do not change. This is because the speed of a wave is determined by the properties of the medium through which it is traveling, and as long as those properties remain constant, the speed will also remain constant.
What happens to the temperature and the speed of the molecules when gas is compressed?
The temperature and speed remain constant.
Does the speed of a car moving in a circular path at 15 mph remain constant Or does the acceleration or its velocity remains constant?
The magnitude of the velocity will be constant however the direction will be constantly changing. The acceleration will remain constant towards the centre of the circle
Do geostationary satellites need a moving dish to receive signals?
No, geostationary satellites do not need a moving dish to receive signals. Since these satellites orbit the Earth at the same rotational speed as the Earth, they remain fixed over a specific point. This allows ground-based satellite dishes to be pointed at a constant angle, enabling them to maintain a stable connection without the need for movement.
Can an object have a varyong speed if its velocity is constant?
No, if an object's velocity is constant, then its speed must also be constant. Velocity is a vector quantity that accounts for both the magnitude (speed) and direction of motion, so if the velocity is constant, both speed and direction will remain the same.
What happens to an objects speed if it travels with constant acceleration?
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
Does velocity stay the same when speed and direction stay the same?
Yes, velocity remains the same when both speed and direction remain constant. Velocity is a vector quantity that includes both speed and direction, so as long as both are unchanged, the velocity will remain constant.
What is the name for an object that will remain at rest or move at a constant speed unless acted on?
A mass
What is a satellite that stays in one location is called?
No satellites stays exactly still as they could not remain in orbit, but probably you are meaning a geostationary satellite. The orbit of these satellites matches the speed of the earth turning underneath them, so they remain above the same geographical point on the earth.
