That taxi will traveled 1500s by carrying the passenger.
Answer:12.8°c
Explanation:
specific heat capacity of copper(c)=0.39J*g°c
Mass(m)=20grams
Quantity of heat(Q)=100joules
Temperature rise(@)=?
@=Q/(mxc)
@=100/(20x0.39)
@=100/7.8
@=12.8°c
Answer:
Vx = 3.10 [m/s]
Vy = 11.59 [m/s]
Explanation:
To solve this problem we must decompose the velocity vector by means of the angle on the horizontal.
v = 12 [m/s]
Vx = 12*cos (75) = 3.10 [m/s]
Vy = 12*sin (75) = 11.59 [m/s]
Answer:
a) System aceleration:
b) Direction of movement:
The block 
down the plane when the acceleration is negative. This occur when:
The block 
up the plane when the acceleration is positive. This occur when:
Explanation:
For the block the move direction is parallel (||) to the plane
(1)
For the block the move direction is vertical (y)
(2)
Both blocks are connected with the same cable, therefore, the tension on the cable and the acceleration is the same for both.
Solving the equation 2 for T:
(3)
replacing (3) in the equation (1)
(4)
solving (4) for a:
Answer:
Pressure increases as you move deeper below earth's surface.
Tempurature increases as you move deeper below earth's surface.
