An airplane in level flight travels horizontally with a constant eastward acceleration of 8.50 m/s2 and a constant northward acc

zloy xaker [14]

Answer:

$d = 3574.3 m$

Explanation:

Given that acceleration of the airplane is

$a_x = 8.50 m/s^2$

$a_y = -28 m/s^2$

initial velocity is given as

$v_x = 83.5 m/s$

$v_y = -15.5 m/s$

now we have displacement in x direction given as

$x = v_x t + \frac{1}{2}a_x t^2$

$x = (83.5)(14) + \frac{1}{2}(8.5)(14)^2$

$x = 2002 m$

Displacement along y direction is given as

$y = v_y t + \frac{1}{2}a_y t^2$

$y = (-15.5)(14) + \frac{1}{2}(-28)(14^2)$

$y = -2961 m$

so the magnitude of the displacement is given as

$d = \sqrt{x^2 + y^2}$

$d = \sqrt{2002^2 + 2961^2}$

$d = 3574.3 m$

All are examples of electric forces except _________. A. a neutron pushing on another neutron B. an electron pushing on a proton

Contact [7]

Answer:

A) a neutron pushing on another neutron.

Explanation:

Neutrons have no charge, therefore, there is no electric force among them. Protons and electrons on the other hand do have electric charge (electrons negative charge and protons positive charge) that generate electric forces between them that can be repelling forces (if the charges are of the same sign), or attractive forces (if the charges are of opposite signs).

A certain planet has a radius of 4990 km. If, on the surface of that planet, a 95.0 kg object has a weight of 591 N, then what i

aniked [119]

Answer:

3743.489 kg

Explanation:

F_g = 591 N

G = 6.674x10^-11 constant of gravity

m_1 = 95 kg

m_2 = unknown

r = 4990*1000 =

F_g = G[(m_1*m_2)/r^2]

591 N = 6.674x10^-11[(95*m_2)/4990^2]

8.855 = [(95*m_2)/4990^2]

355631.472 = 95*m_2

m_2 = 3743.489 kg
