Answer:
250 m/min down the road
Explanation:
Velocity is equivalent to speed but it considers the direction of the object. Velocity is also calculated by dividing the distance travelled by time. Therefore, 
where d and t are distance and time respectively. Given that d is given as 350 m and t is 1.4 s then by substitution 
and the direction is down the road.
Velocity is 250 m/min down the road
Answer:
I think number 3
Explanation:
Or it’s 1 but you just discover stuff in science and don’t argue much so I think it’s number 3, hope this helps, give me A brainliest please. Thanks
Explanation:
The square meter is the SI-derived unit of area. It has a symbol m² (33A1 in Unicode). It is defined as the area of a square whose sides measure exactly one metre.
Given: Wavelength λ = 410 nm convert to Meters m = 4.10 x 10⁻⁷ m
Speed of light c = 3 x 10⁸ m/s
Required: Frequency f = ?
Formula: c = λf
f = c/λ
f = 3 x 10⁸ m/s/4.10 x 10⁻⁷ m
f = 7.32 x 10¹⁴/s or 732 Thz (Terahertz)
Answer:
(a) 142.5 rad/s
Explanation:
Torque = 45 Nm
Moment of inertia = 30 kgm^2
w0 = 0, t = 95 second
(a) Let it is rotating with angular speed w.
Torque = moment of inertia x angular acceleration
45 = 30 x α
α = 1.5 rad/s^2
Use first equation of motion for rotational motion
w = w0 + α t
w = 0 + 1.5 x 95
w = 142.5 rad/s
(b) if he hold rocks, then the moment of inertia change and then angular acceleration change and then final angular velocity change.
