Daniel takes his two dogs, pauli the pointer and newton the newfoundland, out to a field and lets them loose to exercise. both dogs sprint away in different directions while daniel stands still. from daniel's point of view, newton runs due north at 3.40 m/s,3.40 m/s, but from pauli's point of view, newton appears to be moving at 2.30 m/s2.30 m/s due east. what is pauli's velocity relative to daniel, ⃗ pd? v→pd? give your answer in unit vector notation, where north is taken to be the positive - direction and east is the positive - direction.

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

How is zig zagging a form of acceleration?
