The combined mass of Danny+skateboard is 72.5 kg

Explanation:

We can solve the problem by using Newton's second law of motion:

F=ma

where:

F is the net force applied on Danny and the skateboard

m is the mass of Danny+skateboard

a is the acceleration

Here we have the following data:

F = 29 N is the force applied

a=0.4 m/s^2 is the acceleration of Danny and the skateboard

Solving for m, we find their combined mass:

m=\frac{F}{a}=\frac{29}{0.4}=72.5 kg

Rogue waves are created along the "Wild Coast" off the southeast coast of ________, where the Agulhas Current flows directly aga
Vedmedyk [2.9K]

Answer:

Africa

Explanation:

A rogue wave refers to the wave that is twice the height of a significant wave occurring in a particular area. The significant wave height is generally referred to as the mean of the largest one-third of waves existing at a particular time period. In simple words, a rogue wave is much larger than any other waves that occur at the proximity of the same time.

This rough wave describes the interaction between the ocean and sea current and swelling of waves. It takes place when the large swells in the ocean, also known as the Antarctic storms, strikes with the rapidly traveling Agulhas current, and the curved water current focuses on the energy of the waves.

Thus, these Rogue waves are often generated along the southeastern coastal regions of Africa, where there occurs the convergence of Antarctic storm waves and Agulhas Current.

What is true weightlessness ?​
alukav5142 [94]

Answer:

weightlessness, condition experienced while in free-fall, in which the effect of gravity is canceled by the inertial (e.g., centrifugal) force resulting from orbital flight. ... Excluding spaceflight, true weightlessness can be experienced only briefly, as in an airplane following a ballistic (i.e., parabolic) path.
