Idon’t get question number 10 for science

a. matter

b. mass

c. weight

d. gravity does not change

e. determined by gravity

f. location determines amount

It's kind of hard for me to explain but to further understand this topic you can google the deference between mass and weight. Both mass and weight are both related to matter to that's why matter is a.

Weight is determined by gravity because you would way less on the moon that doesn't have that much of a gravitational pull. That's why people jump really high on the moon. that's also why the location determines the amount.

Mass however doesn't change by gravity. When you go to the moon you do not loose more of yourself or become smaller, you stay the same size. That is part of mass.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
