A 1200-kg car is driven around a circular part of a track with a velocity of 8.5 m/s. If the radius of the turn is 42 m, what is the centripetal acceleration of the car?

Under normal temperature and pressure conditions, what type of rock could be formed from weathering in erosion of metamorphic rock

(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?

Aforce of 8,480 n is applied to a cart to accelerate it at a rate of 26.5 m/s2. what is the mass of the cart?
