Knowing the distance may only give you the relative locations between two points, but not the exact location. So, the answer to his question is no. Knowing the distance does not give enough information. If perhaps the coordinates of both points were given, then that would be considered enough information.
Option C.
Ceres is considered the smallest dwarf planet of the solar system.
Answer:
f = 3.97 Hz
Explanation:
Given that,
Centripetal acceleration,
The radius of motion is 0.02 m
The formula for the centripetal acceleration is given by :
The speed of an object in a circular path is given by :
t is time period
Also, f=1/t (f is frequency)
Hence, the frequency of motion s 3.97 Hz.
Answer:
3,500,000 J
Explanation:
WORK = POWER * TIME
WORK= 5400 * 640
=6456000 J = 3,500,000 J
Explanation:
How much thermal energy is released when 500g of steam at 100° C condenses into water and cools to 50°C
Givens: m=0.5 kg
t = 50
c = 2.010
Qtotal = Q1 + Q2
Qtotal = QmcΔt + mLv
Qtotal = (0.5kg)(2.010)(50) + (0.5)(2.3*10^6)
Qtotal = 1.15 * 10^6
The book says that the answer is 1.3*10^6?
