If the radius of curvature of the particle is 4.00 cm, use the information in this problem to calculate the mass of the particle. hint, first compute the velocity of particles that experience no net force in the velocity selector. use this velocity and the information given to compute the mass of the particles. (express your answer to two significant figures.)

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?

Which property is expressed in distance units? o a. period o b. wavelength o c. speed o d. frequency

An airplane is flying with a velocity of 240 m/s at an angle of 30.0∘ with the horizontal, as the drawing shows. when the altitude of the plane is 2.4km,a flare is released from the plane. the flare hits the target on the ground. what is the angle θ?
