Why all planetary objects have different amount of gravity?

1 answer:

3 0

Answer:

Why do scientists usually talk about mass rather than weight? An object's weight is dependent on its mass and how strongly gravity pulls on it. The strength of gravity depends on how far away one object is from another. That's why the same object weighs different amounts on different planets.

True or false: objects fall toward earth at a rate of 9.8 m/s because of centripetal force.

Citrus2011 [14]

Sadly, no. The statement kind of has some appropriate words in it, but it's badly corrupted. Objects don't fall to Earth at a rate of 9.8 m/s, and the force that accelerates them downward is not a centripetal one.

A 5.58 kg object with a speed of 35 m/s strikes a steel plate at an angle of 45.0 degrees with the normal to the plate, and rebo

MAVERICK [17]

Answer:

magnitude of vector is 276.19 kg m/s

Explanation:

The initial momentum is vector of magnitude

$5.58 \times 35 = 195.3 (kg m/s)$ And driven in a coherent manner with initial vector.

same magnitude is momentum after the impact, but it is oriented perpendicularly to initial momentum vector.

So, you have 2 momentum vector of specified magnitude perpendicular to one another.

The contrast between such two vectors is a right angle triangle hypotenuse of 195.3 sides

magnitude of vector is $\sqrt{ 195.3^2 + 195.3^2} = 276.19$
