<h2>
Time taken by dryer to come up to speed is 1.625 seconds.</h2>
Explanation:
We have equation of motion v = u + at
Initial velocity, u = 0 rad/s
Final velocity, v = 5.2 rad/s
Time, t = ?
Acceleration, a = 3.2 rad/s²
Substituting
v = u + at
5.2 = 0 + 3.2 x t
t = 1.625 s
Time taken by dryer to come up to speed is 1.625 seconds.
Answer:

Explanation:
The change in electrical potential energy of a charged particle moving through a potential difference is given by

where
q is the magnitude of the charge of the particle
is the potential difference
In this problem:
- the charge of the particle is 3.00 elementary charges, so

- the potential difference is

So, the change in electrical potential energy is

Answer: The working and answer can be viewed from the screenshots below. Thanks
Answer:
Option D: 1.5in in front of the target
Explanation:
The object distance is
.
Because the surface is flat, the radius of curvature is infinity .
The incident index is
and the transmitted index is
.
The single interface equation is 
Substituting the quantities given in the problem,

The image distance is then 
Therefore, the coin falls
in front of the target
Answer:
B. Landscape B
Explanation:
Shale is fine sediment pressed together to form rock.
Sandstone is larger (sand-grain-sized) sediment cemented together to form rock.
Shale erodes faster, as evidenced by the second attachment. That attachment shows erosion of a rock face consisting of interbedded shale and sandstone. The shale has receded significantly, leaving the sandstone layers with space between them.
