A ball is thrown upwards at a 30 degree angle with a speed of 42 m/s. Find the initial velocity in the x direction.

What is the average speed of a car that travels 40mph for 1 hour and 60 mph in another hour will mark brainliest

Neurons are components of the nervous system of the body that transmit signals as electrical impulses travel along their length. these impulses propagate when charge suddenly rushes into and then out of a part of the neutron called an axon. measurements have shown that, during the inflow part of this cycle approximately 5.6x10^11 na per meter, each with a charge of e enter the axon. how many coulombs of charge enter a 1.10 cm length of axon during this process

An object with a speed of 10 m/s is moving in a direction of 30 degrees above the positive x-axis. the y-component of its velocity vector is most nearly
