Answer : It experience the acceleration is, 7.5m/s^2

Explanation :

By the 1st equation of motion,

v=u+at ...........(1)

where,

v = final velocity = 85 m/s

u = initial velocity  = 23 m/s

t = time = 8.3 s

a = acceleration = ?

Now put all the given values in the above equation 1, we get:

85m/s=23m/s+a\times (8.3s)

a=7.5m/s^2

Thus, it experience the acceleration is, 7.5m/s^2

A compound microscope is made with an objective lens (f0 = 0.900 cm) and an eyepiece (fe = 1.10 cm). The lenses are separated by
Marizza181 [45]

Answer:

-252.52

Explanation:

L = Distance between lenses = 10 cm

D = Near point = 25 cm

f_o = Focal length of objective = 0.9 cm

f_e = Focal length of eyepiece = 1.1 cm

Magnification of a compound microscope is given by

m=-\frac{L}{f_o}\frac{D}{f_e}\\\Rightarrow m=-\frac{10}{0.9}\times \frac{25}{1.1}\\\Rightarrow m=-252.52

The angular magnification of the compound microscope is -252.52

If a an object is traveling at a rate of 5 meters per second squared with a force of 10 Newtons, what is the mass of the object?
Svetllana [295]

Answer:

2 kg

Explanation:

Acceleration = 5 m/s^2

Force = 10 N

Force = mass * acceleration

mass = force / acceleration

mass = 10 / 5

mass = 2 kg
