A scientific probe is a device that is sent to gather information from areas with harsh or dangerous conditions so as to not endanger humans. such devices may be sent to the sea floor, into a volcano, or into space. they collect information on those areas such as pressure, temperature, and makeup of the environment and send that information back to scientists so that they can evaluate and record that collected data.
Answer:
Speed, v = 26.5 m/s
Explanation:
It is given that,
The ball hits the ball at an angle of 40 degrees.
Initial height of the ball, h = 1 m
Vertical distance, y = 3.4 m
Horizontal distance, x = 67 m
The trajectory of the particle in projectile motion is given by :
R is the range of projectile.
Putting all the values in above equation as :
R = 71.3 meters
Now using the formula of the range of the projectile as :
Substituting the values in above equation as :
u = 26.5 m/s
So, the speed with which Fred give to the ball is 26.5 m/s. Hence, this is the required solution.
Answer:
+1/3
Explanation:
The lens equation states that:
where
f is the focal length
p is the distance of the object from the lens
q is the distance of the image from the lens
For a diverging lens, the focal length is negative:
and we also know that the object is placed a distance of twice the focal length, so
So we can find q from the equation above
And the magnification of the image is given by
