The answer
<em>The temperature of substance B will increase more rapidly than the temperature of substance A will.</em>
hope this helps
height = .0970 mm = .00831 inches
Volume = length * breadth * height = 8.5 * 11 * 0.00381
Volume = 0.776985 inches^cube
Answer:
3.025 revolutions
Explanation:
To solve this question firstly we need to calculate the time t
Given the angular velocity and the angular acceleration
The time t = angular velocity/angular acceleration
Converting 50rpm to rad/s
= 50 × 2π /60
=1.67 rad/s
t = 1.67/0.46
t =3.63s
The wheel makes 50 revolutions in one minute
Therefore in 3.63s, it will make
3.63 × 50/60
= 181.5/60
=3.025 revolutions
Approximately 3 revolutions
Answer:
Acceleration of the box is 4.9 m/s².
Explanation:
The free body diagram is shown below.
The weight of the body can be resolved into two mutually perpendicular components as shown. The force responsible for sliding motion of the box along the incline is due to 
acting along the incline.
Therefore, as per Newton's second law of motion,
Net force = 
Now, net force acting along the incline is only
Therefore,
Now, 
Therefore, the acceleration of the box is given as:
Acceleration of the box is 4.9 m/s².
