Answer:

the sides of the wedge are inclined.

Explanation:

The wedge is a triangular simple machine with a blunt face and two inclined faces. The distribution of forces in a wedge is because the sides of the wedge are inclined.

Answer:

$F_f=7.0035\times 10^{-7}\ N$

$F_j=8.45\times 10^{-6}\ N$

Explanation:

(a)

mass of baby, $m_b=4.2\ kg$

mass of father, $m_f=100\ kg$

distance between father and baby, $d=0.2\ m$

Now, the gravitational force on baby due to father:

$F_f=G \frac{m_b.m_f}{d^2}$

$F_f=6.67\times 10^{-11}\times \frac{4.2\times 100}{0.2^2}$

$F_f=7.0035\times 10^{-7}\ N$

(b)

distance between baby and Jupiter, $r=6.29\times 10^{11}\ m$

We have mass of Jupiter, $m_j=1.898\times 10^{27}\ kg$

Now, the gravitational force on baby due to planet Jupiter:

$F_j=G \frac{m_b.m_j}{r^2}$

$F_j=6.67\times 10^{-11}\times \frac{4.2\times 1.898\times 10^{27}}{(6.29\times 10^{11})^2}$

$F_j=8.45\times 10^{-6}\ N$

We find that the gravitational force due to Jupiter is considerably greater than the force due to mass of father.

At what angle does the beam of light fall into the mirror if the beam is reflected

erma4kov [3.2K]

Answer:

The angle of incidence is the angle formed by the incident ray and the perpendicular to the surface. Together, the angle of incidence and the angle the incident ray makes with the surface form a right angle (90 degrees). The angle of incidence is therefore given by the following expression:

Angle of incidence = 90 degrees - angle ray makes with the surface

In your example

Angle of incidence = 90 degrees - 40 degrees = 50 degrees

The law of reflection states that the angle of incidence equals the angle of reflection, which is also measured with respect to the perpendicular to the surface, so

Angle of reflection = Angle of incidence = 50 degrees.

Please help ____________ is the type of energy due to motion.

gizmo_the_mogwai [7]

I believe the answer would be Kinetic Energy. Kinetic energy is defined as energy which a body possesses by virtue of being in motion. We weren’t given answer choices so I don’t have much to work with lol.
