A 0.700-kg pendulum bob passes through the lowest part of its path at a speed of 3.55 m/s. (a) What is the magnitude of the tension in the pendulum cable at this point if the pendulum is 60.0 cm long?

N

(b) When the pendulum reaches its highest point, what angle does the cable make with the vertical? (Enter your answer to at least one decimal place.)

°

(c) What is the magnitude of the tension in the pendulum cable when the pendulum reaches its highest point?

N

for a i used m*v^2/r, but im having the hardest time finding parts b and c, all help is appreciated.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

answer: decibel

explanation:

thermal energy is the answer

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
