A crate is sliding down an inclined ramp at a constant speed of 0.55 m/s. The vector sum of all the forces acting on this crate must point down the ramp. True or false?
Answer:
False
Explanation:
Given: A crate is sliding down an inclined ramp at a constant speed of 0.55 m/s.
To find: whether the given statement is true or false
Solution:
As a crate is sliding down an inclined ramp at a constant speed of 0.55 m/s, net force is equal to 0 and so, the vector sum of all the forces acting on the crate can't point anywhere.
So, the given statement is false.
Which condition causes a hurricane to rotate?
a local storm surge
the Coriolis effect
several large waves
severe coastal flooding
Answer:
b
Explanation:
The Coriolis effect is a condition which causes a hurricane to rotate in a particular direction. Thus, the correct option is B.
What is the Coriolis effect?Hurricanes are the enormous storms which come with a rotating wind speed of about 74 miles per hour. The rotating wind that swirls across the warm water of the tropics and also comes with a terrifying force.
The Coriolis force is an inertial or the fictitious force, which acts on the objects which are in motion within a frame of reference that rotates them with respect to an inertial frame. In a reference frame, with the clockwise rotation, the force acts to the left of the motion of the object. Whereas, in one with anticlockwise or counterclockwise rotation, the force acts to the right of the object. The deflection of an object due to this Coriolis force is called as the Coriolis effect.
Therefore, the correct option is B.

Which waves can travel through space?
OElectromagnetic waves only
OMechanical waves only
OElectromagnetic and mechanical waves O Longitudinal and electromagnetic waves
Answer:
A. electromagnetic waves only
Explanation:
brainliest please? :))
a) Electromagnetic waves only can travel through space
What are electromagnetic waves?Electromagnetic waves are the waves that are propagated by simultaneous period variation of electric and magnetic filed intensity .
Longitudinal wave and mechanical wave require a particular medium to travel , and in vacuum their is no medium that helps the waves to propagate because their is no particle present in vacuum . Hence , their is absence of any matter , wave cannot travel through it .
Because electromagnetic waves do not need molecule to travel and electromagnetic wave are transverse waves and they have oscillating magnetic and electric field thus do not need a medium to travel .
hence , correct option a) Electromagnetic waves only

The speed required of a military jet when taking off from the deck of an aircraft carrier is dependent upon the speed of the carrier and the speed of the wind into which the carrier is moving. The takeoff speed required of a military jet relative to the deck of the carrier is 45 m/s. Determine the acceleration which a military jet must have to take off from the 126-m long runway of the USS Ronald Reagan aircraft carrier.
9514 1404 393
Answer:
8.04 m/s²
Explanation:
A suitable formula is ...
v² = 2ad
a = v²/(2d) = (45 m/s)²/(2(126 m))
a ≈ 8.04 m/s²
The acceleration is about 8.04 m/s².
