In the second half of part i of refraction lab we are looking at the second air/glass boundary. from the law of alternate interior angles, how can we find the incident angle (latex: \alphaα) at the second air/glass interface knowing the transmitted angle (latex: \theta_tθ t) at the first air/glass boundary? group of answer choices latex: \alpha=\theta_t α = θ t latex: \alpha=90^{\circ}-\theta_t α = 90 ∘ − θ t latex: \alpha=90^{\circ}+\theta_t α = 90 ∘ + θ t latex: \alpha=180^{\circ}-\theta_t

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
