A boy ties a rock of mass M to a string and swings it in a circle of radius R with constant velocity v. The plane of the circle makes an angle of θ with the horizontal. Determine an equation for the tension in the string as a function of the constants given and the angle α.α is the angle measured around the circle with α= 0° at the highest point and α = 180° at the lowest point. α increases in the same direction as v.

The seven sisters, seven stars located more than 400 light-years away in the taurus constellation can be seen here with venus and another constellation, orion. the seven stars stay grouped together but seem to move, like the planet venus. why do stars seem to move like planets in the night sky?

An astronaut floating in space is trying to use her jetpack to get back to her space station, but she is being pulled away by a nearby planet, as shown in the image below. her jetpack provides a constant thrust of 310 n. if she angles her jetpack in such a way that it cancels out the vertical force due to the planet's gravity, what is her net horizontal force? thaud 487 o a. 54.8 n toward the space station o b. 212.9 n toward the space station o c. 185.2 n toward the space station o d 956 n toward the space station
