*not sure about the answer but here we go*
Mass = 425 kg
distance = 614.4 m
acceleration = 1.8 m/s²
Answer :
Count Force first.
F = 425 × 1,8
F = 765 N ✅
Now let's count Work.
W = 765 × 614.4
W = 470016 J ✅
Answer:
549.9 ohms, 65.65 watts, the power went up
Explanation: power P = V²/R
v= 190volts , P =62watts
from P =V²/R
62=190²/R
making R the subject
R×62= 190²
62R =36100
R=36100/62
R=586.25 ohms
Resistance of each lamp = 586.26/18 =32.3ohms
a) resistance of the light string now = 17×32.3 = 549.9 ohms
b) P=V²/R
where R=549.9ohms , P=?
P=190²/549.9
P=36100/549.9
P=65.65watts
Power dissipated has increased( went up )
Answer:
<h3>The answer is 53.27 mi/hr</h3>
Explanation:
To find the velocity covered by the car we use the formula
where
d is the distance
t is the time
From the question
d = 554 miles
t = 10.4 hrs
We have
We have the final answer as
<h3>53.27 mi/hr</h3>
Hope this helps you
So that the bridge doesn't break when the summer comes and It expands Or when winter comes and it contracts
Answer; Resonance is an increase in amplitude of a vibration that occurs when external vibrations match an object's natural frequency. The Tacoma Narrows Bridge may have collapsed because of resonance.
