Answer:
Explanation:
initial vertical velocity = 17.5 m/s
using g=-9.81 m/s^2
apply kinematics equation
v1^2-v0^2=2gS
solve for S with v1=0, v0=+17.5
S = (v1^2-v0^2)/2g
=(0-17.5^2)/(2*(-9.81))
= 15.61 m
Answer: Anthony will be warmer after the game.
Explanation :
Anthony and Maelynn are watching a football game outside on a sunny day. Anthony is wearing a black shirt and Maelynn is wearing a white shirt. Anthony will be warmer after the game. The black color is a good absorber of radiation and a bad reflector.
The black color absorbs heat until a thermal equilibrium is attained. So, it is advisable to wear cotton clothes in summers not dark colored clothes.
The magnetic field for a moving charge is the same as the magnetic field from a current element of length, dL, carrying current, I, provided that the quantity qv is replaced by 'IL'.
<h3>
Magnetic force on charged particle</h3>
The magnetic force on a charged particle is determined from the product of the magnetic field strength (B), speed of the charge (v) and magnitude of the charge (q).
The magnitude of the force is caculated using the following formula;
F = qvB
<h3>Magnetic force on a current carrying element</h3>
The magnitude of the force is calculated using the following formula,
F = BILsinθ
- when the angle of inclination = 90 degrees
F = BIL
Where;
- B is the magnetic field strength
- I is current
- L is length of the wire
At equal magnetic force, the magnetic field can be calculated as follows;
B = F/qv = F/IL
Thus, the magnetic field for a moving charge is the same as the magnetic field from a current element of length, dL, carrying current, I, provided that the quantity qv is replaced by 'IL'.

In the digital recording process, the wave is measured or sampled, and the information is converted to mathematical units or quantized. ... The more often the wave is sampled (its sampling rate), the more fully the wave is reproduced. sampling rate. Number of digital samples taken per second.
Answer:
Explanation:
Whether you’re just getting started working out, or you’re looking to add strength training to your cardio routine, weight lifting for beginners can seem anything but simple. There’s a bunch of fitness equipment involved—how exactly do you use that big looped resistance band again?—the moves can be confusing, and you may worry that you might not have the strength to do them.
It’s true that weight lifting can appear intimidating—especially if you’re scrolling through social media and seeing people deadlifting double their bodyweight, pressing a loaded barbell over their head, or banging out Superman push-ups where they fly into the air. But it’s important to remember that those are just highlight reels of people who have been lifting for a very long time. When they first began, you can be pretty sure that they started small. Those explosive push-ups? It’s likely they started as a modified, knees-on-the-floor variation.
And strength training for beginners doesn’t have to start with the goal of getting you to that point, either. If you want to squat superheavy weight, beginning a strength training program can definitely help you get there. But it can also just help you get stronger in ways that will help you in everyday life, too, whether it’s carrying all the grocery bags into the house in one trip or squatting down to the floor to pick up your not-so-cuddly cat.
