Electrons have electrical magnetic fields that require them to have energy that is too intense for quarks
The answer you’re looking for is
D. the frequency
Wasp stinger protection from predators. Peacocks bright plumage to help obtain mate. Owls large eyes to help search for food. Bears fur to help maintain homeostasis
A constant velocity implies the two forces must be equal and opposite.
Friction acts horizontal to the ground, therefore we must find the force applied to the sled rope that acts horizontal to the ground.
Do this by resolving:
Force = 80cos53
The force opposing this is equal, and so also = 80cos53 = 48 N (2 sig. fig.)
