seems strange but... example, a heater, 13 amp fuse... does it draw the same power supply when its full heat as it does when its on a lower setting?...-The fact that an appliance is fitted with a 13 a
Why is torque error likely to be large?
Can an error in one measurement be negated by error in another? Why?-You need to be much fuller in your question.You specify parallel forces.Parallel forces at
If an object is submerged in water, on earth, at a depth of 3km, the Pressure on the object is 2.94 x 107 Pa-Yes, it is
=>By P = P(atm.) + P(depth)
=>P = 1.01 x 10^5 + hdg
=>P = 1.01 x 10^5 + 3000 x 1
I have tried this many times. I honestly dont understand this.-Q=m*L
where m=mass of ice,
L for ice is 333,34 J/g-well 0c is 32f o your gonna need anything above 32f to melt anything....obviously the
A particles position is given by the expresion P=10/3t^3-5/2t^2-20t+10 Determine the position and the acceleration when velocity = 0.-The velocity is the time derivative of the position;
v = dP/dt = 1
I need help with these physics problems please?? They include standing waves, Doppler effect and Decibels, Archimedes Principle,Pascals Law- Pressure and depth, and Fluids. Please explain in detail!!
I need help with these two questions on my homework about acceleration. I need to answer whether their true or false...
If an object has some acceleration, its apparent weight is equal to the actua
Does it stop somewhere or does it keep getting smaller and smaller ? What limits have we reached ?-Its believed that subatomic particles like electrons and quarks are elementary particles, meaning the
21. What is the displacement experienced as you move from, (-3M, 8M) to (7M, -12M)?
A. (10M, -20M)
B. (-10M, 20M)
C ( 10M, 20M)
D ( -10M, -20M)
22. In problem 21, lets say that the displacement t
And if it was could we get into it cause they just annihilate eachother .-Matter and antimatter are just the names we give to the particles that make up our own universe. If parallel universes exitst,
7. A 300N force causes a 77kg object to accelerate. What is the objects acceleration?
A. 0.26 m/s2
B. 3.9 m/s2
C. 755 m/s2
D. 23,100 m/s2-F= m*a
a = F / m = 300 / 77
a = 3.9 m / s^2
B.

Tensile force of the string = 85863.68N
Findperiod and angular frequency for the forth overtone.-Quick answer: fourth over tone has
A particle is travelling with a constant speed. This means
(a) its position remains constant as time passes|
(b) it covers equal distances in equal time intervals
(c)its acceleration is zero
(d) it do
How do you calculate the angular FREQUENCY given the amplitude and the maximum velocity the object travels at (through the point of equilibrium)???-An harmonic oscillator describes a position:
x(t) =
