Answer:
TRUE
Explanation:
Low mass stars last lots longer.
Answer:
3.0 x 10¹ Nm
Explanation:
Torque = F x r
Where F is force applied and r is perpendicular distance from pivot point . r
is also called lever arm
Here F = 15 N and r = 2.0 m
Torque
= 15 N X 2.0 m
= 3.0 10¹ Nm.
Density = (mass) / (volume)
Volume of your block = (5cm x 5cm x 5cm) = 125 cm³
5 gm/cm³ = (mass) / (125 cm³)
Multiply each side by (125 cm³): Mass = 625 gm
Note:
I don't know what kind of frozen substance you're working with,
but maybe you ought to be careful handling it ... I know that's
not water ice you have there. The density of water ice is not
5 gm/cm³. In fact, it's a little less than 1 gm/cm³. That's why
the ice floats in your soda.
The kinetic energy is transferred to thermal energy through friction
